It is wider it is a primary object of the present invention to provide a kind of applicability, the lower paper of cost and plastic sheeting or plastics The oriented film that Low Temperature Thermal seals between film, when the film is with paper or other Film laminateds, without glue coating, by low For warm sealing with that can be completed by compound object contact compound, compound tense will not produce toxic gas.
The object of the present invention is achieved like this：
A kind of preparation technology of plastic sheeting, it is characterised in that the dispensing of plastic sheeting is：Polypropylene component is 55- 95%, the modified by maleic acid anhydride graft thing component of polyolefin is 2-30%, and masterbatch component is 0.5-30%,
The antitack agent component that described masterbatch includes is 0-2%, and antistatic additive component is 0-5%, delustring masterbatch component For 0-20%, titanium dioxide and calcium carbonate components are 0-20%.
A kind of preparation technology of plastic sheeting comprises the steps of：
Dispensing is added in corresponding extruder into 180 DEG C -280 DEG C to be melted, plastify, extrudes and confluxes in T-shaped or clothing Frame pattern head, by die head in 180 DEG C of -280 DEG C of extrusions；
The die head extrudate of supporting layer is cooled down by 10 DEG C -60 DEG C of cooling device, forms diaphragm；
Diaphragm is preheated successively through longitudinal stretching machine, longitudinal stretching and thermal finalization, 100 DEG C of -170 DEG C of preheatings are longitudinal to draw It is 2-6 to stretch multiplying power, and draft temperature is 60 DEG C -160 DEG C, and the temperature of thermal finalization is 90 DEG C -170 DEG C；
Now, the resin of at least one layer of low-temperature heat-sealing layered material molten condition flows out from another die head, equally by polyene The dispensings such as the modified by maleic acid anhydride graft thing of hydrocarbon, which are added in corresponding extruder, to be melted, is plastified, extrude and conflux in T-shaped or Rack type die, extruded by die head, carry out that hot pressing is compound enters back into cross directional stretch preheated zone with the film after longitudinal stretching；
Preheated through 100 DEG C -190 DEG C, cross directional stretch multiplying power is 6-12, draft temperature is 60 DEG C of -170 DEG C of cross directional stretch, temperature It is 90 DEG C of -190 DEG C of progress thermal finalizations to spend scope；
The outermost layer of the supporting layer (side not contacted with Low Temperature Thermal sealing) of composite membrane after cross directional stretch is carried out often Advise corona or flame treatment；
Winding.
