Abstract

The invention discloses a composite membrane for sauce and a preparation method thereof. The composite membrane sequentially comprises a polyethylene glycol terephthalate layer, an aluminum foil layer, an ethylene acrylic multipolymer layer, a double-peak low-density polyethylene layer and a metallocene polyethylene blending and modifying resin layer. The preparation method is characterized by comprising the following steps: dry compounding, preparing the metallocene polyethylene blending and modifying resin layer and blending and compounding. Compared with the prior art, the composite membrane for sauce has high sealing strength, short hot seal time, good sealing effect, good sealing planeness, good pollution resistance, medium resistance, low cost, no delamination, and the like.

Description

technical field [0001] The invention belongs to a composite film and a preparation method thereof, in particular to a composite film for seasoning sauce and a preparation method thereof. Background technique [0002] Seasoning sauce refers to tomato sauce, chili sauce, and meat sauce, which are sour, salty, and spicy. With the accelerated pace of life, the composite film small package of seasoning sauce has been favored by people for its convenient carrying, beautiful appearance, quick use and many other unique advantages. The sub-adhesives are compounded together to form a composite film. This composite material is not resistant to acid and alkali contents, and is easily corroded by sauces and leaks. Contents of the invention [0003] The first technical problem to be solved by the present invention is to provide a composite film for seasoning sauce packaging. [0004] The second technical problem to be solved by the present invention is the preparation method of the ab...
