ANTI BLOCKING ADDITIVES

I. PLASTIC ADDITIVES 

Additives are substances added in a polymer to change some of its properties. Some of the most common are plasticizers used to reduce the polymer's transfer temperature (making it softer in some way), fillers to make it cheaper (usually chalk), ingredients Oil to improve its rheology. Others are used for electrical stabilization reasons or to give polymers a certain ability (for example, photoelectric agents for photolithography).

Various additives and substances are added to give the product desirable properties such as oxidizing and thermal stabilizers, UV stabilizers, chelating agents, secondary stabilizers, plasticizers, additives. antistatic, impact regulator.

II. ANTI BLOCKING ADDITIVES  

Clumping or clumping is the adhesive between the films tightly together, it is difficult to separate them from each other. The cause of this phenomenon can be due to: affinity for each other, opposite charge, due to vacuum ...

This phenomenon causes many difficulties in the production process:

- Difficult to open the mouth of the packaging bags, causing time consuming

- It makes it difficult to put the product inside the bag, sometimes causing a spillage ...

The anti-clumping agent makes the surface of the membrane rough (rough) so that air can easily interfere with the membranes, eliminating the vacuum effect. In some special cases, the antistatic component is added, thanks to the entering of air, the steam will together and block the charge on the membrane surface. Thereby eliminating the clumping phenomenon that has elements due to charge.

The composition of the antifreeze can be either inorganic or organic:

- Inorganic: Silica, Talc, CaCO3, Alumina silicate, Kaoline, Mica, ... Depending on the thickness of the membrane, different inorganic particles are required.

- Organic: Ethylene BisSteramide, Stearyl erucamide, Glycerol monostearate, zinc stearate, teflon, ...
