Abstract

The invention relates to a double-deck plastic bag blow-molding processing technology. The processing technology comprises the following steps: S1, raw material preparation; S2, raw material mixing; S3, raw material pulping blow-molding: adding the premixed raw materials in the step S2 in a presser to be uniformly pressed to obtain the pulp; injecting the pulp into a cavity of a film blowing machine to melt; shooting the inert gas into the molten plastic to enable the plastic melt to fill the cavity, performing gas pressure maintaining to realize continuous film blowing, and then performing film-blowing shaping and cooling to obtain the blow-molding product; S4, flattening and slitting: conveying the blow-molding product in the step S3 to a spreader to flatten, and then slitting to obtainthe processed and customized quadruple shape; and S5, bagging. The double-deck plastic bag blow-molding processing technology disclosed by the invention has the advantages of being recyclable, good inload-bearing effect and excellent in comprehensive performance.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to a double-layer plastic bag blow molding process. Background technique [0002] Plastic products, especially plastic bag products are the most common. When plastic bags are produced and processed, blow molding technology needs to be used. The processing process is to use a flat film blowing machine for blow molding. The formed film is a cylindrical film, and then use a herringbone frame to flatten the cylindrical film. At the same time, the blown film is continuously pulled. Stretch out, and then carry out cutting, sealing and other processes to form plastic bags. [0003] Commonly used food plastic bags are mostly made of polyethylene film, which is non-toxic, so it can be used to hold food. There is also a kind of film made of polyvinyl chloride, polyvinyl chloride itself is non-toxic, but the additives added according to the purposes of the film are often harmful substances...
