Abstract
The invention discloses a shrinkable plastic film for pump, and relates to the technical field of package plastic. The shrinkable plastic film is characterized by being composed of the following components in percentage by weight: 50 to 60% of HDPE, 10 to 20% of LDPE, 10 to 20% of LLDPE, 2 to 8% of VLLDPE, and 3 to 7% of mixed auxiliary additive. A novel formula is adopted, thus the package film has the contractible effect and antirust effect at the same time, the antirust effect is good, the period is prolonged, the contracting force is increased, the package steps are reduced, thus the package cost is reduced, and the economic profits are increased.
Description
Technical field:
The present invention relates to packing plastics thin film technique field, specifically a kind of pump shrink-warp.
Background technology:
Packaging film is mainly formed by the poly-work olefine resin mixing extrusion of several different trades mark, there is puncture resistant, super-strength high-performance, the goods being deposited on supporting plate is wound packaging, make packing material more firm clean and tidy, more there is superpower waterproof action, be widely used in foreign export, papermaking, five metals, plastics chemical industry, building materials, food pharmaceuticals industry.It is known that, generally polyethylene (PE) is divided into high density polyethylene (HDPE) (HDPE), Low Density Polyethylene (LDPE) and linear low density polyethylene (LLDPE) three major types, this three quasi-polyethylene has respective feature, also include ultralow close oligomerisation of ethylene (VLLDPE) etc., it is used alone the thin film that any of which produces and is respectively arranged with its pluses and minuses, but all do not reach preferable effect, in prior art, it is being generally all to use shrink film and rust-preventing film to pump metal product packaging, but packaging film product all only has the unidirectional antirust and function of contraction at present, have to the when of so product packaging product is carried out multi-layer packaging, program is loaded down with trivial details, the cost of packaging is the highest.
Summary of the invention:
The technical problem to be solved is that providing a kind of has the most antirust and contractile function pump shrink-warp,
In order to realize the purpose of the present invention, used following technical scheme:
A kind of pump shrink-warp, it is characterised in that: being become to be grouped into mixing auxiliary additive by HDPE, LDPE, LLDPE, VLLDPE, the content of described HDPE, LDPE, LLDPE, VLLDPE and mixing auxiliary additive accounts for respectively,
HDPE:50%～70%
LDPE:10%～20%
LLDPE:10%～20%
VLLDPE:2%～8%
Mixing auxiliary additive: 3%～7%.
Described mixing auxiliary additive include plasticizer, coloring agent, filler, heat stabilizer, antiplastering aid and modifying agent one or more.
Described modifying agent includes butadiene copolymer zoarium, butyl ester and maleic acid glycosides, and the adding proportion of diene copolymerization body, butyl ester and maleic acid glycosides is 3:2:1.
Described HDPE material, LDPE material, LLDPE material, VLLDPE material and mixing auxiliary additive use three-layer co-extruded mode extrusion molding.
Described plasticizer is chlorinated paraffin.
LDPE (low-density high-pressure polyethylene) is a kind of soft, the resin of white clear.LLDPE (linear low density polyethylene) can strengthen resin resist stretch, penetration, shock resistance and the performance of anti tear so that it is be particularly suitable for making film.HDPE (high density polyethylene (HDPE)) is a kind of degree of crystallinity thermoplastic resin high, nonpolar, and HDPE has excellent resistance to great majority life and the characteristics of chemicals for industrial use, and this polymer is non-hygroscopic and the steam-preventing that had.The present invention uses the mixing auxiliary additive of the VLLDPE and 3%～7% of the LLDPE of the LDPE of HDPE, 10%～20%, 10%～20%, 2%～6% of 50%～70%, the thin film using three-layer co-extruded mode to produce has the advantage of three kinds of materials, meets packaging film and has simultaneously worked as shrinking and antirust equivalent effect.
nullDue to the fact that and have employed new material proportion，Packaging film is made to have simultaneously worked as shrinking and antirust equivalent effect，Due to LLDPE material、LDPE material、VLLDPE material is different with conditions such as HDPE material character and sulfurations，The present invention also added modifying agent，Modifying agent is diene copolymerization body、Butyl ester and the mixture of maleic acid glycosides，Diene copolymerization body、Butyl ester and maleic acid glycosides preferably can merge with polyethylene，And elasticity and the water proofing property of plastic sheeting can be greatly increased，Even if making thin film use one layer of parcel when packing metalwork，Also splitting of plastic sheeting it is not result in，Therefore there is more preferable contractility，Wherein maleic acid glycosides can be as intermediate，LLDPE material can be increased、LDPE material、VLLDPE material melts mutually with the seamless of HDPE material.
The invention has the beneficial effects as follows: due to the fact that and have employed new material proportion, make packaging film simultaneously work as shrinking and antirust equivalent effect, favorable rust preventing effect, cycle stretch-out, contractility increases, and decreases packet assembler, reduces packing cost and improves economic benefit.
Detailed description of the invention:
For the technological means making the present invention realize, creation characteristic, reach purpose and be easy to understand with effect, below in conjunction with instantiation, the present invention is expanded on further.
Embodiment one:
A kind of pump shrink-warp, is become to be grouped into mixing auxiliary additive by HDPE, LDPE, LLDPE, VLLDPE, and the content of HDPE, LDPE, LLDPE, VLLDPE and mixing auxiliary additive accounts for respectively,
HDPE:60%
LDPE:15%
LLDPE:15%
VLLDPE:5%
Mixing auxiliary additive 5%.
Mixing auxiliary additive includes plasticizer, coloring agent, filler, heat stabilizer, antiplastering aid and modifying agent.
Modifying agent includes butadiene copolymer zoarium, butyl ester and maleic acid glycosides, and the adding proportion of diene copolymerization body, butyl ester and maleic acid glycosides is 3:2:1.
HDPE material, LDPE material, LLDPE material, VLLDPE material and mixing auxiliary additive use three-layer co-extruded mode extrusion molding.
Plasticizer is chlorinated paraffin.
The ultimate principle of the present invention and principal character and advantages of the present invention have more than been shown and described.Skilled person will appreciate that of the industry; the present invention is not restricted to the described embodiments; the principle that the present invention is simply described described in above-described embodiment and description; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements both fall within scope of the claimed invention.Claimed scope is defined by appending claims and equivalent thereof.
