It is a bag that addresses the issue of high costs associated with clean bags while being positioned between regular plastic bags and clean bags, alleviating concerns about additive contamination in regular bags.
【No additive bleed-out】 In general poly bags, additives are added to improve productivity and bag-making suitability, but by using additive-free LDPE, it is possible to avoid additives. 【No additive adhesion to contents】 Since it is made from additive-free raw materials, there is no additive bleed-out on the outer and inner surfaces of the bag (the product contact surface), so there is no worry about additive particles adhering to the contents during filling or packaging. 【Optimal for general environmental usage levels】 This product is ideal for customers who are not using clean rooms but are concerned about particles, and find clean bags to be too costly.

basic information
General plastic bags contain secondary additives such as "antioxidants," fatty acid-based "lubricants," and silica-based "anti-blocking agents" to improve film productivity and bag processing suitability. These additives begin to bleed out from the interior of the film to the exterior (both the outer and inner surfaces of the bag) immediately after production. "Additive-free LDPE bags" use additive-free raw materials that do not contain any additives. Since they are made from additive-free materials, there is no bleeding of additives to the outer and inner surfaces (product contact surfaces) of the bag, eliminating concerns about additive particles adhering to the contents during filling or packaging.

While storing the product in a bag, a white powder-like substance was found adhering to the contents. Upon checking the bag that was used for storage, it was found that an additive had bled out from the bag and seemed to be adhering to the product, leading to a consultation. After switching to a bag made of additive-free LDPE, no transfer to the product was observed.
