Adopting S-coating on metal chips! Introducing issues and the effects of improvements!
Here is an introduction to a case study on the adoption of "S Coat," which provides excellent antistatic effects. There were issues where the inner wall of the bag came into contact with metal chips, causing additives in the static-resistant LLDPE film (such as antistatic agents, AB agents, AO agents, etc.) to adhere, resulting in discoloration and degradation. By adopting this product and using additive-free LLDPE, it was possible to eliminate the migration of additives even when the contents came into contact with the film, resulting in zero losses due to discoloration and degradation. 【Case Overview】 ■ Contents ・Metal chips ■ Material composition before improvement ・Transparent vapor-deposited PET/DL/static-resistant LLDPE ■ Material composition after improvement ・Transparent vapor-deposited PET/S Coat/DL/additive-free LLDPE *For more details, please refer to the PDF document or feel free to contact us.

basic information
【Summary of Other Cases】 ■Issues - It was reported that when using bags that had been stored for a certain period, the static prevention effect decreased, causing contents to stick to the inner walls of the bag and become difficult to remove, or the film and contents to repel each other electrically and scatter. - Contact with metal chips on the inner wall of the bag caused additives in the static prevention LLDPE film (such as antistatic agents, AB agents, AO agents, etc.) to adhere, resulting in discoloration and deterioration. ■Effects of Improvements - The antistatic layer of the S-coat is sandwiched and protected by two plastic films, ensuring that there is no degradation of antistatic performance and that its effect lasts semi-permanently. - By adjusting the application amount of the S-coat agent, a high level of antistatic properties was imparted, allowing for smooth filling and removal of products at all times. - Since additive-free LLDPE was used, there is no migration of additives even when the contents come into contact with the film, resulting in zero losses due to discoloration and deterioration. *For more details, please refer to the PDF document or feel free to contact us.
