Embodiment Construction

[0026] The present invention will be further explained below in conjunction with specific embodiments.

[0027] A production process of FFS flow channel exhaust packaging bag, comprising the following steps:

[0028] S1: Ingredients, selection, screening of plastic raw materials that meet the GB / T 10004-2008 standard, and adding modifiers, anti-aging agents and curing agents;

[0029] S2: Layering, the plastic raw material for the outer layer is 80% metallocene polyethylene or metallocene ethylene-ethyl acetate, and 20% polyethylene terephthalate blend is added, and the middle layer is made of raw materials 80% linear low density polypropylene or linear low density polyethylene, add 20% butene copolymer or terpolymer, use 20% ethylene-ethyl acetate, 20% silicone oil, 10% spit Temperature, 10% silicone, 10% polyphenylene ether, 20% modified adhesive resin EVA;

[0030] S3: Melting, sending the raw materials of each layer to the microwave high-temperature equipment correspondi...

Abstract

The invention discloses an FFS runner exhausted packing bag production process. According to the FFS runner exhausted packing bag production process, produced packing bags can bear 70-80 DEG C high-temperature filling and dozens of times of transportation and transfer, and meanwhile, is flat, clean and attractive in surface, rich in pattern content, clear in color, anti-counterfeiting, good in sealing performance, moisture-proofness, waterproofness and antifouling performance, applicable to stacking in the open and convenient to transport and store; also, the produced packing bags can preventmelting, caking, weight loss and quality reduction of packed products, is free from softening and deformation at high temperature or cracking and breakage at low temperature, resistant to ultravioletand stable in color; compared with traditional woven bags, the FFS runner exhausted packing bag production process can double the storage and shelf life of the produced packing bags as well as the packed products.

Description

technical field [0001] The invention relates to the technical field of packaging bags, in particular to a production process for FFS channel exhaust packaging bags. Background technique [0002] Packaging bags refer to bags used to pack various supplies, making the goods convenient to transport and store during the production and distribution process. [0003] At present, blister-forming packaging products are mainly prepared from a single unidirectional or biaxially stretched polyolefin material, and are mostly used in the packaging fields of food, fruit, medicine, and medical equipment. However, due to the performance limitations of polyolefin materials, most blister-molded packaging products have poor product performance, such as low heat resistance, insufficient mechanical strength, and poor gas barrier performance. [0004] Traditional blister forming co-extrusion film packaging products are mainly made of polyethylene, polypropylene, PVC, polyester and other single po...
