Abstract
The invention discloses a high-strength food packaging film which is composed of the following raw materials in parts by weight: 50-90 parts of high-density polyethylene, 0.5-5 parts of filler, 1-10 parts of plasticizer, 0.5-10 parts of modifier, 0.5-10 parts of metallocene, 3-10 parts of linear polyethylene and 0.1-2 parts of edible pigment. The high-strength food packaging film has high bearing load, and is widely used in food transfer packaging bags.
Description
Technical field
The invention belongs to chemical technology field, particularly a kind of high strength food product packing film.
Background technology
The output of China's plastics film accounts for 20% of plastics ultimate production, is increase of production one of classification faster in plastics.Along with the fields such as China's packaging, agricultural not only increase the demand of plastics film, the demand estimating China plastics film every year by with more than 9% speed increment, its market outlook are very wide.
In Plastic Packaging Materials, the market demand amplification of thin-film material is maximum, accounts for 46% of Plastic Packaging Materials total amount.Plastic film mainly comprises: heat shrinkable package film, winding package film, food sterile packed film, fruit-vegetable plastic wrap, liquids packaging film etc.Along with China's plastics film industry equipment improves constantly, the advanced level reaching developed country had, emerge a collection of product innovation, such as, biaxially oriented film as substrate of composite package not only overcomes the situation of long-term import, and annual also outlet about 300,000 tons now, earn foreign exchange more than 30 hundred million dollars.In China, the quantity development of the packaging film manufacturing concern of scale rapidly, has reached 2240 at present.
Food sterile packed film refers to and can tolerate the food packing film that food (as milk preparation, beverage, food flavouring) carries out the ultrahigh-temperature needed for instantaneously sterilising, this packing film can make food at not adding preservative agent, without when refrigeration, there is longer shelf-life, this is a new technology, is also one of plastics packed developing direction.Food sterile packed is divided into two kinds, the aseptic large packing bag of a kind of to be capacity be 5 ~ 1000L, and the composite membrane of bag mainly adopts PET aluminium plating film and PE film to be composited; Another kind is aseptic cup type packaging, uses PP/PE/EVA/PVDC/PS multilayer copolymerized compound membrane, and wherein PP is protection tunic, and EVA is tack coat, and PVDC is oxygen barrier layer.
