Which one is stronger glue or tape

Different adhesives - differences in adhesives for PP tape

Anyone who buys adhesive tape as a private person will not be too interested in it different adhesives with which you can coat the PP carrier film. The main thing is that it bakes somehow, that's probably the motto here. But what exactly are they Advantages and disadvantageslike that Differences between the various adhesiveswhich are the most common on the market and are all suitable for PP tape? And what have we made of it at activaTec?

  • Acrylate
  • Hot melt
  • Natural rubber

Maybe you've heard it before. But what is the difference between these adhesives and PP tape actually? What are the properties of the types of glue and what are their advantages and disadvantages? Which adhesive do we use at activaTec for our Packing tape? We clarify all ‘of these questions in this article. If you don't want to go into so much detail, you should go for the Differences between PP and PVC adhesive tape look more precisely. In addition, we at activaTec have developed our own adhesive formula, which combines the best properties of all ‘of the above adhesives, but without the corresponding disadvantages. Our in-house PK6 adhesivewho has the positive properties of Acrylate, hot melt & natural rubber united in order from the standard PP carrier film To make an ultra-strong tape, which is generally considered to be stronger PVC tape is in no way inferior. On top of that, activaTec also offers the so-called. PVC tapewhose name already suggests that it is neither the typical PP nor the PVC adhesive tape. This consists of one extra-thick PP film(35my)which is similar to PVC in terms of its feel and is coated with PK6 adhesive. It achieves an impressive adhesive strength for packages up to 100 kilos, but is at the same time significantly cheaper than PVC adhesive tape - with at least the same performance.It is also more environmentally friendly, as PP film rots by itself in the open air. Unlike normal PP film, the PK6 adhesive formula also ensures that the PCV adhesive tape is temperature-resistant from -30 to +60 degrees Celsius, is ideal for long-term storage and also sticks to recycled cardboard. The latter takes care of the Hotmelt content in the PK6 formula. All things that you have to do without with normal PP adhesive tape, because you save a lot on the price. This compromise comes to an end with activaTec. Here you get both: Inexpensive and environmentally friendly adhesive tape With high adhesive strength, elasticity and tear resistance. But what exactly are the common adhesives from which the special activaTec formula is mixed?

Acrylate adhesive - soluble in water or with a solvent

First of all, when it comes to acrylate, a distinction must be made between two types of adhesive that contain several different components.Dispersion acrylate adhesiveis water soluble and market leader while Solvent acrylic adhesiveis not quite as environmentally friendly. The leading acrylate adhesives in Europe are based on water dispersion and do not release any environmentally harmful substances when disposed of. In Europe almost only available in ready-mixed form for raw material suppliers, which is why the adhesive properties can hardly be influenced.

Advantages of acrylate adhesive (PP film):

  • It rolls easily and is available with both a loud and a quiet rolling noise
  • High transparency and ideal for white cardboard boxes
  • Continuous adhesion and good adhesive strength, as the adhesive penetrates into the fibers of the cardboard after a while, creating a very strong bond (particularly suitable for long-term storage / and long transport routes)
  • Good UV and aging resistance

Disadvantages of acrylic adhesive (PP film):

  • Low initial tack; Acrylate needs time to bond with the cardboard surface
  • Low shear strength
  • Very temperature sensitive

Ideal for: light to medium-weight cardboard boxes, longer transport routes

Not so good for:Transports through different climate zones, short intralogistics transports

Hot melt glue

The hotmelt adhesive is usually used for the cheapest PP adhesive tapes and packaging tapes. The name already suggests: hotmelt adhesive is aHot melt adhesive. This does not mean that you now have to melt the tape before you can apply it to the packages. Rather, the name is an indication of how the adhesive is made and how it comes onto the PP carrier material: namely, by melting the synthetic granulate into an adhesive mass at high temperatures. This is then applied to the PP carrier material at a temperature of approx. 90 ° C.

Advantages of hotmelt adhesive (PP film):

  • Sticks very quickly - immediate adhesion (different from acrylate)
  • Good adhesion to steel
  • (Conditionally) free of solvents
  • Tape is easy to unroll

Disadvantages of hotmelt adhesive (PP film):

  • Also very temperature-sensitive and therefore low performance in extremes(very warm / very cold)
  • Low UV and aging resistance
  • Loud noise when rolling
  • The glue turns slightly yellow when stored for a long time (not a nice customer experience)

Ideal for: light to medium-weight cardboard boxes, for short storage and shipping

Not so good for:Transport through different climate zones, long-term storage and long transport routes

Natural rubber

You can guess three times. Correct! For the production of the natural rubber adhesiveNatural product rubberused. What perhaps less people already know: this material is a milky sap (latex) that is obtained from the rubber tree. The rubber is then combined with aSynthetic resin, which ensures the adhesive strength of the natural rubber adhesive, dissolved in solvent and then processed. After coating, the solvent used is in a so-calledRecovery plant to over 95% recovered and reused in the cycle. Natural rubber is by far the most environmentally friendly alternative, because together with the PP carrier film, disposal or recycling is unproblematic, as it decomposes even in the open air. Adhesive tapes based on natural rubber are considered to be those in the market highest quality products.

Advantages of natural rubber adhesive (PP film):

  • Wide range of applications, there are many variants: e.g. strongly and weakly adhesive variants possibleH
  • Faster and stronger hold than the other adhesives, very high adhesive strength and adhesion
  • High shear strength
  • Relatively good temperature resistance
  • Safe and permanent closure on difficult cardboard surfaces (also recycling cardboard & foil)

Disadvantages of natural rubber adhesive (PP film):

  • Low UV and aging resistance
  • Color differences possible because it is a natural product
  • Adhesive may turn yellow if it is stored for a long time

Ideal for: Medium-weight and even heavy cardboard boxes, also for export goods and transport through different climate zones. Because it unrolls quietly, it is also welcome as machine tape, suitable for storage in the freezer area

Not ideal for:Long term storage

PK6 - the best of all

Since you constantly have to compromise with typical adhesives, we at activaTec asked ourselves why not just develop a new adhesive that combines all the advantages without the disadvantages. We use a special mixing ratio of the three adhesives, which means that our PP adhesive tapeseither

  • suitable for long-term as well as short-term storage
  • environmentally friendly in disposal and production
  • UV and aging resistant
  • Temperature resistant (-30 degrees to +60 degrees)
  • both strong immediate and long-term adhesive strength
  • and rolling quietly

are. And if they are not yet quiet enough, we can also provide you with Silently unwinding packaging tape and matching Tape dispenser.
