What additives are usually used in plastic packaging bags?

In order to improve the performance of plastic bags, it need to add some additives its stability during the production process,commonly used additives are the following:

Heat stabilizer, can improve the thermal stability of the plastic material,then can improve its adaptability to different temperatures.

Plasticizers,can improve toughness and ductility of the packaging bags, not easy to be shredded.

Anti-static agents, on the surface properties of the bag make improvements to prevent the generation of static electricity.

Colorant,can change colors, improve the appearance, at the same time improving its optical properties.Wide variety of coloration products for packaging applications.Suitable for long-term coloration and visual appeal.

Anti-oxidants,can prevent the occurrence of aging and prolong bag's life.

Anti-scratch additives,are capable to bind effectively to the polymer matrix and to avoid migration.

Master batch fillers, effectively reduce production costs of plastic bags by filling in the material.

Additives help to improve surface properties of polymers like scratch resistance and surface smoothness. Higher output and better processing of compounds can easily be achieved by applying processing aids.Packaging is also an essential element of content protection, in particular for food and beverage,for example,flour is always packed in PP woven bags(or named PP bags).Therefore, packaging materials do contribute to aesthetic enhancement, convenience-in-use functionality, content protection and preservation and low additional costs for mass production.
