Preferably, a kind of easily tore film includes following components raw material: 65 parts of metallocene PE, gathers 25 parts of polyamide
13 parts of propylene, 1.5 parts of polyethylene opening agent, 1.5 parts of slipping agent, 1.5 parts of polyamide opening agent.
The present invention also provides a kind of production technologies of easily tore film, comprising the following steps:
Step 1: raw material is added in proportion in casting machine hopper and is heated up, raw material is stirred and melted crowded by casting machine
Out；
Step 2: the material after extrusion is flowed out by distributor, die head, later by casting roller, the first one-step forming of chill roll；
Step 3: the film after pre-profiling carries out sided corona treatment by corona machine, and is rolled up by winder harvest semi-finished product, later
Semi-finished product volume is transported into curing room curing and is shaped into finished product within 72 hours.
Further, the temperature of die head is maintained at 240-260 DEG C in the step 2.
Compared with prior art, the beneficial effects of the present invention are:
Raw material of the present invention be it is nontoxic, odorless, metallocene PE in raw material is in toughness, transparency, hot sticky
Property, heat-sealing temperature etc. etc. be substantially better than conventional polyethylene, the slipping agent of addition increases extensibility, keep its easy-to-draw not easily broken,
