[sovereignty] 1 A low shrinkage polyamide film in boiling water is formed by mixing, vacuum drying, melting, extrusion, slicing, and vertical and horizontal stretching. It is characterized in that the proportion of the film is mixed by (3 ~ 5)% m-xylene diamine 6 resin and (97 ~ 95)% polycaprolactam resin

[Abstract] the invention relates to a boiling water low shrinkage polyamide film, which belongs to the field of chemical material processing, in particular to the formula screening of polyamide resin, so that the resin has a low shrinkage during hot water treatment, and can meet the requirements that the polyamide film does not curl and does not delaminate during boiling water treatment. Polymer melt gear pump is one of the important means and does not peel, And it can ensure a certain gas barrier and a certain mechanical strength. It is suitable for all kinds of food packaging materials with beautiful external surface and soft canned food packaging bags
