Abstract
The invention discloses a toxic-free thermal-shrinking thin film which is composed of following components including, by weight, 90-94 parts of PVC resin powder, 4-5 parts of ABS, 4-5 parts of butyl stearate, 1.6-1.8 parts of zinc stearate, 0.6-0.8 parts of paraffin, 2-3 parts of CPE, 6-8 parts of DOP, 2-2.6 parts of epoxidized soybean oil and 2-3 parts of a stabilizing agent. By means of reasonable improvement of the formula, the invention provides the toxic-free thermal-shrinking thin film which is toxic-free and odor-free, is easy to recycle, is suitable for being used in direct packaging of products including foods, beverages, electronic appliances, machines, hardware and the like, and is safe and healthy.
Description
Technical field
The present invention relates to a kind of nontoxic heat-shrinkable film.
Background technology
Heat-shrinkable film is a kind of good film packing material, and it has following advantages: the transparency that (1) is good, and the commodity that can client be allowed directly to have seen packaged, are convenient to client's picking commodities; (2) be close to commodity profile, go for the packaging of the commodity of different shape, pack content is extensive; (3) thief-proof property, dirt resistance are excellent; (4) multiple commodity packaging in a heat shrinkable package bag, the loss of indivedual small item can be prevented, is also convenient to client and carries; (5) different resins and formula is selected, the heat-shrinkable film of different physical strength and function can be produced, both can be used for the internal packing that intensity is lower, commodity weight is less, also can be used for the machinework of the higher freight container of desired strength, the Transport Package of material of construction etc.Heat-shrinkable film appears at the Germany in World War II the earliest, uses PVDC, is used for packing weapon, prevents from getting rusty after two-way stretch.So heat-shrinkable film is just used in after suitability for industrialized production in industrial goods packaging from the beginning, just heat-shrinkable film is used for food product pack afterwards, such as: PVDC casing film is used for sausage packaging etc.Heat-shrinkable film utilizes film the vertical or horizontal energy storage stretched is in the film under elastomeric state, the memory effect had the form before two-way or unilateral stretching utilizing thermoplastics to have, can recover the function of the form before stretching to reach packaging object when running into heat.
In the prior art, also there is virose deficiency in thermal shrinkable sleeve film, and existing heat-shrinkable film haves much room for improvement.
Summary of the invention
For the problems referred to above, the invention provides a kind of nontoxic heat-shrinkable film, there is nontoxic characteristic.
In order to solve the problem, technical scheme provided by the invention is:
A kind of nontoxic heat-shrinkable film, be made up of following each composition and weight ratio thereof, PVC resin powder: 90-94 parts, ABS:4-5 part, butyl stearate: 4-5 parts, Zinic stearas: 1.6-1.8 parts, paraffin: 0.6-0.8 part, CPE:2-3 part, DOP:6-8 part, epoxy soybean oil: 2-2.6 parts, stablizer: 2-3 parts.
Preferably, be made up of following each composition and weight ratio thereof, PVC resin powder: 92-94 parts, ABS:4-5 part, butyl stearate: 4-5 parts, Zinic stearas: 1.65-1.8 parts, paraffin: 0.6-0.8 part, CPE:2-3 part, DOP:6-8 part, epoxy soybean oil: 2.2-2.6 parts, stablizer: 2-3 parts.
Preferably, be made up of following each composition and weight ratio thereof, PVC resin powder: 93 parts, ABS:4.5 part, butyl stearate: 4.2 parts, Zinic stearas: 1.75 parts, paraffin: 0.65 part, CPE:2.8 part, DOP:7 part, epoxy soybean oil: 2.5 parts, stablizer: 2.6 parts.
