Anti-rusting and shrinking packaging plastic film for pump

Abstract

The invention discloses an anti-rusting and shrinking packaging plastic film for a pump, and relates to the technical field of packaging plastic films.The anti-rusting and shrinking packaging plastic film is characterized by comprising, by weight, 76%-90% of LLDPE, 8%-18% of LDPE and 1%-7% of mixed assisting additive.According to the anti-rusting and shrinking packaging plastic film, as the new material proportion is adopted, a packaging film has the equality effects of shrinking and rusting preventing at the same time, the anti-rusting effect is good, the period is prolonged, the contractility is increased, packaging procedures are reduced, packaging cost is reduced, and economic benefits are increased.

Description

Technical field: [0001] The invention relates to the technical field of packaging plastic films, in particular to a rust-proof shrink packaging plastic film for pumps. Background technique: [0002] The packaging film is mainly composed of several different grades of polyolefin resin mixed and extruded. It has puncture resistance, super strength and high performance. Strong waterproof effect, widely used in foreign trade export, paper making, hardware, plastic chemical industry, building materials, food and medicine industries. As we all know, polyethylene (PE) is usually divided into three categories: high-density polyethylene (HDPE), low-density polyethylene (LDPE) and linear low-density polyethylene (LLDPE). These three types of polyethylene have their own characteristics. There are advantages and disadvantages of using any one of the films produced alone, but all can not reach the desired effect. In the prior art, shrink film and anti-rust film are usually used in the p...

As we all know, polyethylene (PE) is usually divided into three categories: high-density polyethylene (HDPE), low-density polyethylene (LDPE) and linear low-density polyethylene (LLDPE). These three types of polyethylene have their own characteristics. There are advantages and disadvantages of using any one of the films produced alone, but all can not reach the desired effect. In the prior art, shrink film and anti-rust film are usually used in the packaging of metal products for pumps. However, At present, the packaging film products only have one-way antirust and shrinkage functions, so when packaging the product, the product has to be packaged in multiple layers, the procedure is cumbersome, and the packaging cost is also high.
