Plastic film processing and application of plastics additives category

Plastic additives is to improve resin processing properties and performance and added chemicals. Plastic additives normally used more than a dozen categories, along with the increase of plastic varieties, expansion and use of technological advances in processing, additives types and varieties are increasing.
In plastic film processing and use of plastics additives to be added. Because some resin or film products suited to their inherent properties of its processing requirements needed to add auxiliary merely needs to change its workability; while some materials better performance of its processing, and product performance is not up to our requirements, which also add additives to alter its performance. Of course, these two roles are complementary, sometimes in order to simultaneously achieve both purposes. First introduced here can change the plastic packaging film performance additives.organic pigments
General requirements for compatibility with additives in general, only the additives between the resin has good compatibility, to make additive term, stable, uniformly present in the film, to function effectively. If compatibility is not good, is prone to "migrate" phenomenon. Performance in the liquid auxiliaries to as "sweat", manifested in solid auxiliaries as "blooming" phenomenon. But sometimes less stringent requirements on the film, the still allow some of its lack of compatibility, such as the compatibility between the filler and the resin is not good, but as long as the small particle size filler, the film still can basically meet the performance requirements, of course, if with a coupling agent or surfactant to handle it, the better to give full play to its functions. But there are some improvements in the film surface properties such as antiblock additives, antistatic agents requires it to have slight mobility, so as to play a role in the surface of the film.one pack stabilizer
Durability Durability is required additives persist in the film without substantially little or no losses, while the loss of additives, mainly through three ways: evaporation, extraction and migration. Mainly with the molecular weight of additives, the solubility in the medium and the solubility in the resin. Suitability for certain resins processing conditions more demanding processing conditions, such as high processing temperatures, you should consider whether the selected additive decomposition of additives on processing equipment without corrosion.
