Method for performing vacuum plastic suction molding on plastic sheet composite materials

Abstract

The invention relates to a method for performing vacuum plastic suction molding on plastic sheet composite materials. The method comprises the following steps of preparing the plastic sheet compositematerials; and performing vacuum plastic suction on the plastic sheet composite materials in a mold to obtain the product. The method for performing vacuum plastic suction molding on the plastic sheetcomposite materials provided by the application is suitable for wine box inner supports, cosmetic inner supports, jewelry inner supports, tea caddy inner supports, high-grade wooden boxes, gel cassette inner supports, paper box inner supports and the like; the plastic sheet composite materials obtained through the method are wide in application and environmental-friendly; and under the situationthat after being repeatedly folded, the plastic sheets are cracked completely and are mutually separated, the effect of supporting can also be achieved because of connection of the composite materials, so that the plastic sheet composite materials obtained by the method can be still used after being repeatedly folded, and besides, the plastic sheet composite materials are anti-scraping, cold-resistant and heatproof, convenient to transport and have toughness.

Description

technical field [0001] The invention belongs to the technical field of packaging materials, and in particular relates to a vacuum-absorbing molding method for plastic sheet composite materials. Background technique [0002] The inner layer of traditional packaging (wine bottles, cosmetics, jewelry, etc.) is made of plastic sheets under electrostatic flocking to complete high-temperature blister molding. During flocking, static electricity is used to electrostatically adsorb small flannel particles on the surface of the plastic sheet. During the transportation process, fluff will fall off, causing personnel to inhale particles, resulting in sneezing or coughing. After a long time, operators will get itchy skin and get sick. [0003] Traditional packaging is directly formed by plastic sheet, which is not beautiful enough. The plastic sheet has no luster and elasticity, and cannot be used as a high-end product. At the same time, the existing packaging inner support products ar...

Problems solved by technology

[0002] The inner layer of traditional packaging (wine bottles, cosmetics, jewelry, etc.) is made of plastic sheets under electrostatic flocking to complete high-temperature blister molding. During flocking, static electricity is used to electrostatically adsorb small flannel particles on the surface of the plastic sheet. During the transportation, the fluff will fall off, causing the personnel to inhale the particles, resulting in sneezing or coughing. After a long time, the operator will get itchy skin and get sick

[0003] The traditional packaging is directly formed by plastic sheet, which is not beautiful enough, and the plastic sheet has no luster and elasticity, so it cannot be used as a high-end product

At the same time, the existing packaging inner support products are single, especially the synthesis of static flannelette (the plastic sheet is charged with positive static electricity, and the flannelette sprayed with negative charges is attached to the plastic sheet, and there is glue on the plastic sheet) time-consuming and labor-intensive, and In the later use, some fluff ions will fall off on the surface of the product

The plastic inner support will be worn and scratched during transportation, and it will be deformed or easily damaged in places with cold weather in the north
