Abstract
The present invention discloses one high strength film specially for container buffer air bag. The high strength film includes reinforcing layer and heat sealed layer adhered successively. The reinforcing layer is made of high strength polyethylene resin, and preferably high strength polyethylene resin of density greater than 0.93 g/cu cm and melting index lower than 1.0. The reinforcing layer is made of high density polyethylene, metallocene low density polyethylene, medium density polyethylene, reinforced polyethylene or superhigh molecular weight polyethylene. The heat sealed layer is preferably made of the mixture of metallocene low density polyethylene in 30-40 wt%, linear low density polyethylene in 30-40 wt% and low density polyethylene in 20-40 wt%. The film specially for container buffer air bag has high mechanical strength, excellent heat sealing performance and good airtight performance.
Description
Technical field
The present invention relates to a kind of special-purpose film, particularly relate to a kind of high-strength thin-film of container buffer air bag special use.
Background technology
Container buffer air bag is used the gas principle that rises, and forms cushion layer between goods or pile, avoid between the goods since again friction, collision, the extruding in the transportation cause the damage of goods, in order to avoid cause unnecessary loss.Therefore require the container buffer air bag film special to have the mechanical strength height, can bear performances such as elevated pressures after heat sealability that pulling strengrth is big, good and the inflation of one-tenth bag.And the film ubiquity mechanical strength of domestic production at present is low, pulling strengrth is little, and heat sealability is poor, can not bear higher defectives such as pressure after the inflation of one-tenth bag.Consequently the container buffer air bag major part of China's use adopts the airbag of direct import, another part adopts the high-strength thin-film of import to produce some airbags, cause the productive costs of container buffer air bag higher, need to use a large amount of foreign exchanges, and then influence a large amount of uses in market.
Therefore Development and Production goes out a kind of high-intensity film, solves the requirement of strength of container buffer air bag, thereby can be widely used in the film of container buffer air bag, becomes the technical matters that those skilled in the art press for solution.
Summary of the invention
Technical matters to be solved by this invention is to disclose a kind of special film for container buffer air bag, to overcome the above-mentioned problem that existing film exists.
The technical scheme of technical solution problem of the present invention is as follows:
A kind of special film for container buffer air bag comprises enhancement layer adhered to one another successively and hot sealing layer.
Enhancement layer is to select the poly-vinyl resin with higher-strength for use, preferably adopts density＞0.93g/cm
3, the ultra-strong polythene resin of fusion index≤1.0.
Said enhancement layer is selected from one of high density polyethylene (HDPE), metallocene low density polyethylene (LDPE), medium density polyethylene, enhancing polyethylene, ultra-high molecular weight polyethylene.
Preferred employing mol wt is 200000～250000 high density polyethylene (HDPE); Mol wt is 160000～180000 the poly-low density ethylene of metallocene; Mol wt is 180000～230000 medium density polyethylene; Mol wt is 350000～450000 enhancing polyethylene; Mol wt is the ultra-high molecular weight polyethylene more than 1000000.
It is the low density polyethylene (LDPE) compound of 30～40% metallocene ldpe resin, 30～40% linear low density polyethylenes and 20～40% that hot sealing layer preferably adopts percentage by weight.Have lower heat-sealing temperature and heat seal strength preferably like this.
Preferred employing mol wt is 160000～180000 metallocene ldpe resin;
Preferred employing mol wt is 150000～180000 linear low density polyethylene;
Preferred employing mol wt is 100000～150000 low density polyethylene (LDPE);
Special film for container buffer air bag of the present invention adopts the JIS-1702 standard to detect, and meets quality loop.
Special film for container buffer air bag of the present invention adopts upper blowing method well known in the art to be prepared, through the once-combined moulding of multi-layer co-extruded technology.
Special film for container buffer air bag of the present invention has higher mechanical strength, and pulling strengrth is greater than 27MPa, good heat sealability and good air tightness.Film become can bear higher pressure behind the bag and do not leak, broken, can be made into a large amount of freight container cushion pockets, the article in the protection freight container can be because of the slip in the transportation, collision and damaged.This product development has vast market prospect.
