Embodiment Construction
[0064] In one embodiment of the present invention, the packaging film has a three-layer structure of RF-PA / nano-polymer or EVOH / PA, wherein the nano-polymer is one of nano-PA, nano-EVOH or nano-PET.
[0065] In another embodiment of the present invention, the packaging film has a five-layer structure of RF-PA / nano-PA / MXD6 or EVOH / PA / RF-PA.
[0066] The production method is as follows: select a plasticizing extruder according to the number of layers of the food packaging film bag, extrude through a co-extrusion die, and wind and water cool (up blowing or down blowing) and then draw and coil.
[0067] The production method of the heat-shrinkable stretch film is as follows: through multiple plasticizing extruders, extruding through a co-extrusion film head, down-blown water cooling, synchronous biaxial stretching, heat setting, and rolling to obtain a heat-shrinkable stretch film.
[0068] The transparency of the product of the present invention is that the total light transmitta...
