does the stretch film not have enough viscosity?

Stretch film has the characteristics of good softness, high viscosity and high puncture resistance. However, due to the low cost performance, it is seldom used in practice. Will there be a situation when the viscosity is not enough? Let's see:

As a viscosifier of LLDPE stretch film, it has a large range of viscosity adjustment, convenient adjustment and obvious comprehensive advantages of sex and price. PIB and its base material are currently the most common viscosifier in the production of LLDPE stretch film. Due to its incompatibility with LLDPE stretch film, PIB will gradually migrate to the surface of stretch film to generate viscosity.

Stretch film requires the adhesion to have both good peel adhesion and good lap adhesion. The higher the stripping viscosity is, the harder the pallet is to unpack and the better the airtightness of stretch film is. The higher the adhesion of the lap joint, the less the longitudinal displacement of stretch film is likely to occur. Therefore, in order to obtain a firm package, the stripping adhesion of stretch film and the adhesion of the lap film need to reach an equilibrium.
