The production process of pe powder-free packaging bag and its pe powder-free packaging bag

Abstract

The invention discloses a PE powder-free packaging bag production technology and a PE powder-free packaging bag obtained by the PE powder-free packaging bag production technology. The PE powder-free packaging bag comprises, by mass, 29-72% of LLD-PE7042, 14-42.5% of LLD-PE21HS and 14% of LD-PE260GG. Through adjustment of a raw material blending ratio and reasonable optimization of production technology temperature control, a blow molding technology is finished without use of any antiblocking agent and slipping agent and thus high-transparency and powder-free products are obtained and product quality is effectively guaranteed. The PE powder-free packaging bag production technology has simple and easy processes, can be realized easily, has high production efficiency, can fast prepare the PE powder-free packaging bag which has high transparency, good surface gloss and no white powder in the bag interior, does not use raw materials such as an antiblocking agent and a slipping agent, effectively reduces a cost and can be widely popularized and used.

Description

technical field [0001] The invention belongs to the technical field of packaging bag production technology, and in particular relates to a production technology of PE powder-free packaging bag. Background technique [0002] Packaging bags refer to bags used to pack various supplies, making the goods convenient to transport and store during the production and distribution process. Widely used in daily life and industrial production. [0003] PE is the abbreviation of polyethylene, which is a thermoplastic resin obtained by polymerization of ethylene. Polyethylene is odorless, non-toxic, feels like wax, has excellent low temperature resistance (the lowest operating temperature can reach -70 ~ -100 ° C), good chemical stability, and can withstand most acid and alkali erosion (not resistant to oxidation properties) acid), insoluble in common solvents at room temperature, low water absorption, excellent electrical insulation properties. It is currently widely used in the manuf...

Problems solved by technology

However, although these PE packaging bags can roughly meet the requirements of use, due to their composition and manufacturing process, an appropriate amount of anti-opening agent and slippery agent must be added, so that white powder is attached to the finished PE packaging bag, resulting in adhesion on the surface. On the product, it affects the quality of the product, especially when it is used on the product packaging of black clothes or other black objects
