Abstract

The invention discloses a synthetic paper schoolbag with anti-counterfeiting and heat preservation functions. The synthetic paper schoolbag consists of a main bag body, a first side bag body, a second side bag body and two straps, wherein the first side bag body and the second side bag body are symmetrically arranged on the left and right sides of the main bag body; the two straps are symmetrically arranged on the back surface of the main bag body; the side surface of the main bag body, the first side bag body and the second side bag body are made of a Dupont TM TYVEK R synthetic paper / heat preservation cotton / PEVA heat preservation film three-layer structural material; the non side surface of the main bag body and the straps are made of a Dupont TM TYVEK R synthetic paper / air cushion inaterlayer / Dupont TM TYVEK R synthetic paper three-layer structural material; the edges of the first and second side bag bodies are seamed in an overlapping manner by using the Dupont TM TYVEK R synthetic paper / heat preservation cotton / PEVA heat preservation film three-layer structural material and the Dupont TM TYVEK R synthetic paper / air cushion inaterlayer / Dupont TM TYVEK R synthetic paper three-layer structural material of the main bag body. The synthetic paper schoolbag is light, handy, waterproof, dampproof and high in healthiness and environment friendliness.

Description

technical field [0001] The invention belongs to the technical field of daily necessities, in particular to a synthetic paper school bag with anti-counterfeiting and heat-preserving functions. Background technique [0002] dupont TM Tyvek Made from spunbond fibers, synthetic paper is tough, durable, stronger than normal paper, more cost-effective and versatile than normal fabrics. Tyvek made of high-density polyethylene combines the advantages of paper, fiber and film, and has been applied in different fields. dupont TM Tyvek It has the characteristics of high strength, light weight, good flexibility, smoothness, not easy to shed, high opacity, and waterproof, strong chemical corrosion resistance, friction resistance, anti-aging, etc., making it an ideal material for wide application. [0003] At present, the schoolbags on the market are almost made of fiber and leather. These materials are difficult to take into account multiple functions. For example, ordinary fibers...
