For the choice of the adhesive Sleeve for shrink sleeve labels to be the most suitable possible, we must heed a series of determining factors. In this article we are going to talk about the different variables that must be heed when choosing it.
Choose the Adhesive Sleeve for shrink sleeve labels according to…
The type of plastic film
You have to take into account the type of plastic that makes up the film that we have to glue. The most frequent are PVC and PET, while OPS and PLA are less frequent. Depending on the manufacturer, the composition and additives contained in the plastic can change the behavior of the adhesive different, in some cases because the film layer is too permeable and some particles can pass through the film. A softer adhesive formula may help in these cases.
Compatibility with the primers
Depending on the type of PET used or theusage surface coatings such as ink or priming, the adhesive find problems in performing its sealing function. In some cases, custom development to find compatibility with the HP Primer 030, (Adhesive Sleeve GC) may be a solution, but in others it could be very difficult to solve.
Homologation the product with production machines
Our formulations are tested on the best-known machines on the market: DCM, Karville, Accraply (Stanford), Emprom, etc., and with different dosing systems, but on many occasions, the speed of evaporation of the adhesive plays a fundamental role in the finished of sleeve. That is why our range of formulations is wide, – including the option of the marker additive, to inspect under a special UV lamp – regarding the rate of evaporation of the adhesive, thus allowing it to be adapted to the production requirements of the client and their type of machine.
To choose Adhesive Sleeve take into account the machine and the dosage of the product
The regulation of the machine and the dosage of the product are important variables during the sealing process, to apply the necessary quantity of the product that ensures the correct bonding of the two layers of film and at the same time that the area does not overflow once the adhesive it is laminated between them. The surface tension of the film, the pressure of the rollers as well as the dosing flow plays an important role that the machine operator must observe.
Our range of products encompasses complex formulations to adapt to manufacturing needs, avoiding that the customer has to handle different chemical products, with the difficulty and risk that the final mixture is not always homogeneous.
Ibeslab is aware of the critical role played by the shrink sleeve seaming, and therefore we make our wide range of formulations and logistics services available to you anywhere in the world.
