Products are typically transported in boxes, but it matters how the box shipped is sealed. If this is not done professionally enough, the goods can be damaged during transport, which is both inconvenient for the customer and financially damaging for the company. The ideal case sealer automates this key operation. Let's see how!

Packaging technology is a rather colourful field that has undergone huge changes over the last decades. With the growth of online shops and the rise of online shopping, speed is becoming increasingly important, but fortunately not at the expense of security.

Thanks to innovation, packaging can now be made even more efficient with the help of complex systems. Boxes are assembled by the box erecting machine, so workers only must concentrate on filling them, if not automatically. Once the goods are in the box, it is sealed by the case sealer machine and the finished packages can be sent to the warehouse on a conveyor belt.

What is a case sealer?

During the sealing process, the workers insert the open box into the sealer that automatically seals it and loads the next box. Thanks to the automated sealing process, the quality of the packaging is guaranteed. Case sealers are durable and low-maintenance solutions when it comes to packaging. Flanker offers a wide range of case sealers, such as the 3M-MaticTM 7000A 3PH 380/415V case sealer ACCUGLIDE 2+2IN, or the 3M-Matic™ 8000A 1PH 220/240V case sealer ACCUGLIDE 2+2IN.

The advantage of a case sealer is that it is flexible in adapting to the size of the boxes, and automatically detects the parameters of the box and adjusts based on these parameters.

Sealing is possible with several types of case sealers. There are manual adhesive tape applicators, semi-automatic bottom-up sealing machines with manual or automatic adjustment, semi-automatic box erecting and filling stations, and automatic box erecting machines with bottom-up adhesive case sealing.

Selecting the optimal tape is crucial during the process. There are many types to choose from, for example brown, transparent, paper, and of course different sizes. See what box sealing tapes are available from Flanker!

What aspects should you consider when choosing a case sealer?

Choosing the right case sealer is not a simple task. Let's look at the factors you should consider before making your decision.

• What is the type of the box? What are its parameters? What is the material? Cardboard? Corrugated?
• Are all boxes the same size or are the sizes different?
• How is the box closed? Will the folding of the tabs be automatic? What width of the tape is needed, and will there be overlapping?
• What capacity is required? What are the performance level requirements? How many boxes will need to be closed per day?
• What will the box contain? How much load will the box sealing machine be subjected to?
• What other requirements are there? Will it fit into an existing system?

In which cases is it appropriate to use a case sealer?

There are cases when a case sealer can significantly facilitate and speed up the packaging process. For example, webshop operators, and manufacturers who need to package their products safely in the shortest possible time.

What are the advantages of a case sealer?

The biggest advantage of case sealers is their speed and efficient operation. A semi-automatic machine can seal as many cans in 5 minutes as it can manually in 30 minutes. It logically follows that it increases packaging capacity significantly, by up to a third. Operation is simple and fast, just switch it on and it's ready to work. It helps to optimise the amount of adhesive tape used and thus reduces costs.

What does a professional, good case sealer look like?

The following requirements can be made of modern case sealers:

• Practical: a case sealer is easily variable, can be built in both left and right-hand versions, and its modules are interchangeable.
• Safe: the construction of a good quality machine is simple, with few components, which also means that it requires little maintenance and therefore minimum downtime. Its operation is safe in terms of both efficient production and operation.
• Offers functional variability: modern case sealers can be easily expanded with other modules to meet your needs.

With the rise of online shopping, the issue of appropriate packaging is also gaining in importance. However, by using a quality case sealer, you can be sure that the parcel you send will arrive undamaged.

Polyurethane (PU) glue is a very versatile adhesive, making it a popular choice among our customers. What exactly is polyurethane adhesive, what types are there and when should it be used? Here are the most important things to know.

Polyurethane

Polyurethane is a generic term for materials that are held together by urethane, or carbamate bonds. This versatile polymer material can have different properties depending on the type of material, which makes it suitable for use in construction, furniture, and automotive applications. It is available in various forms, including coatings, foams, and adhesives. Let's find out what you need to know about polyurethane adhesive!

Polyurethane adhesive

Polyurethane adhesive is a synthetic, resin-based adhesive that hardens when it comes into contact with water. As soon as the adhesive is applied to the surface, it starts to expand and the excess can be easily removed with a knife. Achieving the final solid state, a permanent bond can take up to 1 hour, so the materials must be tightly pushed together.

This type of adhesive can be used at temperatures above +15 degrees Celsius. Should you try to use it colder than this, the adhesive's properties may change. It is worth knowing that polyurethane is antiseptic, which means that it prevents mold and fungi from growing.

Let's learn about the benefits of polyurethane adhesive!

It can be used to bond different materials

One of the huge advantages of this type of adhesive is that it can be used to bond different materials together. Whether it's wood, plastic, metal, or any other material, polyurethane adhesive provides a stable bond.

Waterproof and watertight

Although moisture is required for curing, once the adhesive has set, it is no longer damaged by water or precipitation. This is an extremely advantageous property, which allows it to be used outdoors and even as a gap-filling sealant.

Practical use

The characteristic of the adhesive is that it does not cure all at once, but takes about 20 minutes to harden. This is an advantage because, in this time interval, it is still possible to move the materials around and find the right position and setting. Overall, it takes 1 hour for the final bond to form, and this long bonding time should always be taken into account when applying the adhesive.

Gentle

The polyurethane adhesive does not damage the surface of the materials, does not leave marks, and does not bump up. This means that it can be used safely even when laying parquet or wooden floors. 

Weather resistant

Resistance is a very important property, and polyurethane adhesive is a leader in this respect. It is resistant to frost, air and heat, extreme temperatures, and substances such as petrol and oil.

What can it be used for?

As described above, polyurethane adhesive is a versatile option for bonding tasks.  It can be used to glue ceramics, stone slabs, marble, porcelain, and mosaics, and repair swimming pools, boats, and toys. It is suitable for fixing PVC edges, and panels on furniture or windows.

Used in the manufacture of sandwich panels, for fixing artificial grass and rubber mats. An excellent choice when different elements such as timber beams, plinth units, guttering, or plastic need to be joined together. It can also be used for furniture restoration, shoe repair, flooring, and car seals.

The characteristics of the adhesive

Polyurethane adhesive is composed of 10-15 elements, the ratio of which determines the final properties of the adhesive, such as viscosity, adhesion, and curing speed. Different colouring agents are used to give different colours to adhesives for different applications, e.g. amber and brown for wood adhesives, and black or grey for metal adhesives.

Types of polyurethane adhesive

There are two types of polyurethane adhesives: one-component and two-component. What do you need to know about them?

The one-component polyurethane adhesive

These adhesives typically form a flexible bond, adhering surfaces together with a resilient layer that resembles rubber. They are less harmful to health than other adhesives because they contain fewer harmful substances.

It has the advantage of being an environmentally friendly solution that absorbs vibrations, creating a flexible bond rather than a rigid one. The adhesives can be easily resealed and reused later. If they accidentally get on the skin, there is no need to worry, they can be easily removed.

These one-component adhesives are also commonly found in households, used for repairing shoes, and carving. Easy to use, all that is needed to start polymerisation is a little moisture provided by the air or the material to which it is applied.

The two-component polyurethane adhesive

This type of adhesive is made up of two components which, when they come together, start a chemical reaction and form a bond. The two components come in separate packages, so they must be mixed before use. Particular care must be taken to ensure that the correct proportions are used, as this is the only way to achieve a satisfactory result. The polymerisation is not triggered by the moisture but by the other component.

It is essential to be aware that the B component of two-component adhesives contains epoxy resin, which means that it can be harmful to health, for example by causing an allergic reaction.

It is a preferred adhesive for floor tiling, for example, as it can be used to correct minor substrate irregularities. It bonds quickly and creates a very strong adhesion. It is easy to work with and good value for money.

Using the adhesive

With a one-component adhesive, the material is ready to use, but with a two-component adhesive, you start by mixing the ingredients. It is a good idea to remove any dirt, dust, or grease from the material and then apply the adhesive in a thin layer. If you are working with paste, use a spatula to spread it.

The layer of glue mustn't be too thick, i.e. that it is applied thinly. If you are working with a porous surface, apply two coats, wait a few minutes after the first coat, and then apply the next coat.

For a certain period, about 20 minutes, the materials can still move, so when you have found the right fit, fix them. Once the joint is formed, trim off the excess with a knife.

Whether it's a building or renovation project, in addition to the main raw materials, several seemingly minor elements are essential to a good result. In this article, we will introduce one such small but even more important material, the glass cloth electrical tape, which is essential for gluing small gaps and holes when joining plasterboard sheets. Let's see what you need to know about it!

What is a glass cloth electrical tape?

Glass cloth electrical tape is used to reinforce the joints between plasterboard panels and to reinforce holes and cracks. It is a very effective solution for sealing joints and gaps. It has a very high tensile strength, which gives it a long life and a secure hold, and it adheres well even on dusty surfaces.

Such tapes can be self-adhesive, made of glass fibre, or even paper.

Glass cloth electrical tape, as the name suggests, is made of glass tape, which is very strong and durable. It is resistant to chemical attack, extreme temperatures, and corrosion. In most cases, it is attached with some other material, such as glue or resin, to further increase its durability.

Its uses can be very diverse. It is mainly used in the construction industry to reinforce plasters, and plasterboarding and to repair cracks. It is also used in the construction of cars, boats, and aircraft, to make vehicles even more resistant. High strength can also be a particularly important aspect in sports equipment, so it is not surprising that it is also used to reinforce bicycles, fishing rods, and skateboards, for example, and is also a popular material in various artistic sectors, such as sculpture.

A wide range of glass cloth electrical tape is available. They come in different thicknesses and sizes depending on where and in what situation they are used.

Use of glass cloth electrical tape

The use of glass cloth electrical tape requires some practice, but there is no need to be intimidated by it. The adhesive material should be applied and then the tape can be easily smoothed in while it is still fresh and has not started to dry. Once this is done, wait for the surface to dry. Once dry, the glued surface is sanded overusing a special sanding grid. This should be done with particular care as it may damage the bonding agent.

The advantages of glass cloth electrical tape

With so many advantages, it's no wonder that glass cloth electrical tape is the preferred choice for professionals. Let's get to know these benefits!

Good adhesion

The ease with which the tape adheres to the adhesive is very important for efficiency. Thanks to its special structure, this type of tape has a very good adhesion and is easy to work with.

Protection against cracks

Due to the nature of the material, cracks can easily develop, and it is therefore important to use as many means as possible to prevent them. If you use glass cloth electrical tape in combination with adhesive materials, you can prevent the formation of gaps and cracks.

Versatile application

Glass cloth electrical tape is popular because of its versatility. In addition to the uses already mentioned above, it can also be an excellent choice for special situations, such as fire barriers.

Pneumatic tools are very efficient due to their unique functioning. Pneumatic sanders can be used to remove surface defects and unevenness effectively. In this article, we've gathered all the relevant information that you need to know about these tools.

What are pneumatic tools?

Pneumatic tools are air-powered. What this means in practice is that they build up an air system to which you can connect various special tools, such as a chisel, drill, angle grinder, stapler, impact wrench, or even a nail gun.

The great advantage of such air-based systems is that they can be installed on the columns at a much lower cost, to which various tools can then be easily attached.

Pneumatic disc sanders

A pneumatic disc sander is a tool that is commonly used to reduce and smooth the surface of various types of materials. The principle of operation is that the machine uses air pressure to generate the energy by which the grinding head rotates, causing the abrasive cloth, sanding disc, or sandpaper to perform a grinding or sanding motion.

These pneumatic sanders help to perform various sanding operations efficiently and effectively. Their use is advantageous as they are powerful and reliable thanks to the pneumatic power source.

Types of pneumatic sanders

Orbital sanders

Orbital grinders are very versatile tools, suitable for grinding and polishing surfaces of wood, metal, and other materials. Thanks to the rotary movement, smooth sanding can be achieved, whether it is for more vigorous or finer sanding.

Belt sanders

Belt sanders are longitudinal sanders, suitable for demanding and uniform sanding of larger workpiece surfaces. The performance of the machines and the quality of the sanding are determined by the grain size of the abrasive used.

Disc senders for covering angles

These special types of sanders can be used for a variety of applications. They are generally used for grinding and cutting surfaces of materials. Their compact, practical design and the different sizes of their discs allow them to handle almost any type of material.

Vibratory sanders

Vibratory sanders perform an irregular rotary motion, making them ideal for fine grinding of large surfaces. They are also used for grinding edges and corners. Their compact and lightweight design makes them convenient to use and ideal for places where access is limited.

Die grinders

Die grinders or sanders have different sizes and types of attachments, which allow the use of different grinding discs or cutting discs. The grinder can be used for grinding, smoothing, or cutting surfaces of metals, wood, or other materials. Pneumatic die grinders are widely used in various industries and trades, such as automotive, woodworking, engineering, and construction. In addition, the ergonomic design and light weight allow working for longer periods without fatigue.

Benefits of pneumatic sanders

Safety

In most cases, sanding tools are used in the work area, in the workshop, where dust can collect, liquids can spill or even conductive metals can be in the immediate environment. These are all sources of danger, especially when working with power tools. With a pneumatic sander, however, there is no need to worry about damaging the cord or accidentally cutting it, and the equipment itself does not pose any electrical hazard to the user.

Compact design

Pneumatic tools, including grinders, are typically preferred because they are compact and easy to use. They are strong, yet lightweight, thanks to the aluminum frame that houses a durable steel pneumatic motor and a composite handle for added comfort.

It is therefore much lighter, easier, and faster to work with, making the work much more efficient. For comparison, while an electric sander weighs just over 3kg and has a power output of 710W, a pneumatic sander weighs just under 2kg and has a power output of 1700W.

Efficiency

The main indicator of a sander is its material removal capacity, i.e. the time it takes to remove a given amount of material to be sanded. It is generally true for sanders that the best performance is achieved at a given power. Modern machines have an adjustable speed, so when you increase the speed, the airflow, the speed, and, of course, the speed of the abrasive increases.

Durability

Pneumatic grinders are very robust, they can withstand cutting, grinding, deburring, weld preparation, seam removal, and grinding. Electric grinders have several limitations, such as the fact that they cannot be used in humid environments and are significantly exposed to the negative effects of dust and abrasive particles in the air. Pneumatic devices, on the other hand, are more robust, can be used in humid environments and dust does not affect the engine. This makes their use more advantageous in foundries where extreme temperatures are encountered, in drilling rigs where water, salt, and cold are a challenge, and in windmill blade manufacturing where composite particles are a threat.

Trustworthiness

Pneumatic grinders are characterised by their tremendous durability, longevity, and reliability. Their simple design also means they are easy to service and maintain. Generally speaking, maintenance is required after 60-120 hours of operation, and the carbon brushes should be replaced at the very least. In the case of professional or industrial machines, the carbon brush should be replaced even less frequently, every 200 hours in the former case and every 2000 hours in the latter. With less servicing, the machine will be up and running for a shorter period, making it more cost-effective to operate.
