Choosing vinyl resin to improve the quality of high temperature cooking bags

May. 23, 2019

In this paper, the grade and category tables of high temperature cooking bags under different conditions are summarized.

Vinyl Resin for Steaming and Boiling-resistant bags:Good ester solubility, and compatibility with polyurethane resin, the hydroxyl-modified vinyl resin is steaming and boiling resistant, having excellent dispersibility to pigments, providing combined strength.

High temperature cooking bags according to relevant ambient temperature.

According to GB/T10004-2008 "Plastic Composite Film for Packaging, Bag Dry Composite, Extrusion Composite", the products are classified according to the use temperature as ordinary grade, water boiling grade, semi-high temperature boiling grade and high temperature boiling grade:

Foreign classification

       The temperature grading of cooking bags (referred to as "High Temperature Laminates" by the FDA in the United States) is comparatively consistent with the foreign practice of dividing them into three grades.
