Abstract
The invention discloses a breathable plastic film, which belongs to the field of packaging materials. The breathable plastic film comprises the following raw materials by weight: 15 to 25 parts of polyolefin elastomer, 50 to 70 parts of polyolefin copolymer and 15 to 25 parts of polypropylene. The polyolefin copolymer comprises the following raw materials by weight: 40 to 45 parts of an ethylene-propylene copolymer and 55 to 60 parts of an ethylene-butylene copolymer. The polypropylene comprises the following raw materials by weight: 70 to 80 parts of co-polypropylene and 20 to 30 parts of homo-polypropylene. The thickness of the breathable plastic film is 50 to 75 mu m. The breathable plastic film has microporous structures distributed in high density; when a packaging bag is prepared from the breathable plastic film for storage of a product, water vapor and like generated by the product can be smoothly discharged; and the breathable plastic film has good flexibility and elasticity, is environment-friendly and nontoxic and meets needs of usage.
Description
Technical field
The present invention relates to a kind of plastics film, especially a kind of breathable plastic film, belongs to wrapping material field.
Background technology
At present, plastic packaging bag is owing to having good storage characteristics and portability, can rapidly and efficiently product be stored to carrying, that in our daily productive life, applies is more and more extensive, traditional film is after making packing bag, micropore due to the special construction that does not have high-density to distribute in packing bag, therefore in storage, some have respiratory product in packing bag, in the time of as vegetables and fruit, can cause the water vapor that vegetables and fruit respiration produce rapidly and efficiently and smoothly to discharge, water vapor can cause the product in packing bag to accelerate to produce rotten, reduced the time that vegetables and fruit store, vegetables and fruit can not be stored for a long time, reduced economic benefit, existing Packaging Method is generally to punch in packing bag, the water vapor that in packing bag, product produces can be discharged smoothly, but punching can cause product in packing bag can not evenly carry out exhaust in packing bag, and can cause the pollutent of storage condition by the aperture in packing bag, the product in packing bag to be polluted, reduce the degree of cleaning of product.Breathable plastic film on existing market, product complicated, and the micropore of producing on film can not evenly control, and the flexibility of film and elasticity can not reach the needs of packing, and life cycle is shorter.
The patent of invention that application number is 201310481250.7 provides a kind of novel waterproof air previous plastic film, in the composition of raw materials of making waterproof ventilated membrane, added the natural mineral filler with features, do not affecting under the situation of permeability, the air-permeable envelope that air-permeable plastic film water-proof function aspect is produced than traditional technology improves nearly 50%, but the micropore in the packing bag of this kind of air-permeable envelope production can not be uniformly distributed, and the pliability of film and elasticity can not reach the needs of packing, and life cycle is shorter.
Summary of the invention
Technical problem to be solved by this invention is to overcome existing above-mentioned deficiency in prior art, and provides a kind of permeability good, meets the breathable plastic film of packing of product needs.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is:
A breathable plastic film, is characterized in that: the raw material that described breathable plastic film comprises following weight parts: 15 ~ 25 parts of polyolefin elastomers, 50 ~ 70 parts of polyolefin copolymers, 15 ~ 25 parts of polypropylene; The raw material that described polyolefin copolymer comprises following weight parts: 40 ~ 45 parts of ethylene propylene copolymers, 55 ~ 60 parts of ethylene-butylene copolymers; The raw material that described polypropylene comprises following weight parts: 70 ~ 80 parts of Co-polypropylene, 20 ~ 30 parts of homo-polypropylene; The thickness of described breathable plastic film is 50 ~ 75 microns.
Further, described Co-polypropylene comprises at least one in atactic copolymerized polypropene and block copolymerization polypropylene.
Further, described polyolefin elastomer adopts polyethylene octene elastomer.
The present invention compared with prior art, have the following advantages and effect: the composition of a kind of breathable plastic film of the present invention is simple, the thin film stability of producing is high, on film, can evenly produce the micropore of the special construction of high-density distribution, guarantee that packing bag that film makes is when storage has respiratory product, can discharge outside packing bag by the water vapor that product respiration is produced rapidly and efficiently, improved the storage time of product in packing bag, improved economic benefit, breathable plastic film environment-protecting asepsis, utilize packing bag that breathable plastic film is made to meet the needs of food storing, and breathable plastic film contains polyolefin elastomer, flexibility and the elasticity of film have been increased, improved the life cycle of breathable plastic film, meet the needs of packing.
