Abstract
The invention discloses an enhanced polyethylene heat shrinkable film, and relates to the technical field of packaging material production. The heat shrinkable film is prepared from raw materials including, by weight, 80-90 parts of ethylene-butylene copolymer, 80-90 parts of high-density polyethylene, 50-80 parts of linear low-density polyethylene, 0.02-0.08 part of antioxidant, 0.08-0.12 part of auxiliary antioxidant and 0.05-0.12 part of heat stabilizers. The high-density polyethylene and low-density polyethylene with a low melting index are added into the linear low-density polyethylene to perform modification, a high-strength polyethylene material is obtained, and mechanical property is greatly improved. Compared with an existing similar product, the enhanced polyethylene heat shrinkable film has the advantages of lower melting index, larger molecular weight and higher strength, is lower in production cost, has outstanding puncture resistance and excellent aging resistance, and meets the requirements of high-strength polyethylene film resin for machining property and various physical mechanical properties.
Description
Technical field
The present invention relates to wrapping material production technical field, be specifically related to a kind of enhancement type polyethylene heat-shrinkage film.
Background technology
Along with the sustainable development of China's economy, the demand of packaging industry to heat-shrinkable film is increasing, range of application also constantly expands, because heat-shrinkable film not only has good over-all properties in mechanical property, packaging, storage, transport, protection against the tide and outward appearance etc., be easy to reclaim and the recycling of raw material, meet the requirement of environmental protection, and improve packaging efficiency on automatic packaging line, reduce comprehensively packaging cost, just progressively replacing traditional packaging becomes loose mail assembly package first-selection.
Heat-shrinkable film can be widely used in the one integral piece assembly package of the products such as pop can, mineral water, various beverage, cloth, heat-shrinkable film product snappiness is good, impact resistance, tear strength is strong, moistureproof, shrinking percentage is large, the functions such as the transparent display of commodity can be met, again save cost, become alternative carton package development trend.Existing polyethylene heat-shrinkage film has mainly to be adopted LDPE and produces, and LDPE is lower due to tensile strength, during the assembly package of the heavier product of heat-shrinkable film packed weight using it to prepare as mineral water, beverage, easily breaks.And prepare high strength heat-shrinkable film, can meet to weight packaging needs.
Summary of the invention
It is high that problem to be solved by this invention is to provide a kind of intensity, polyethylene heat-shrinkage film with low cost.
To achieve these goals, the technical scheme that the present invention takes is a kind of enhancement type polyethylene heat-shrinkage film of providing, it is prepared from by the raw material of following weight part: ethylene-butylene copolymer 80-90 part, high density polyethylene(HDPE) 80-90 part, linear low density polyethylene 50-80 part, oxidation inhibitor 0.02-0.08 part, auxiliary antioxidant 0.08-0.12 part and thermo-stabilizer 0.05-0.12 part.
Preferably, it is prepared from by the raw material of following weight part: ethylene-butylene copolymer 85 parts, high density polyethylene(HDPE) 90 parts, linear low density polyethylene 60 parts, 0.05 part, oxidation inhibitor, auxiliary antioxidant 0.09 part and thermo-stabilizer 0.08 part.
Preferably, the melt flow rate (MFR) of described Low Density Polyethylene is 0.3-0.8g/10min, and density is 0.940-0.950g/cm
3.
Beneficial effect of the present invention: the Low Density Polyethylene that the present invention adds high density polyethylene(HDPE) and low melt index in linear low density polyethylene carries out modification, obtain high strength polyethylene material, mechanical property is greatly improved, compared with existing like product, there is melting index lower, molecular weight is larger, the feature that intensity is higher, production cost is lower, product has outstanding paracentesis resistance, excellent ageing resistance, meets the processing characteristics required by high-intensity polyethylene film resin and every physical and mechanical property.
Embodiment
The technique means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the present invention further.
embodiment 1:
