Background technology
Along with improving constantly of people's living standard, the fresh-keeping and nutritive value of food is had higher requirement.In order to satisfy people the kind of food and the requirement of nutrition, food circulation all over the world increases, and is its corresponding, and the storage of food and shelf-life require also to have prolonged.Therefore, food processing industry has the requirement of higher barrier for the film of food casing, to guarantee the fresh taste and the quality of food.The article packing of some special industries also needs the very flexible package of high barrier, as medicine and medical supplies.Meanwhile, from the packing environmental angle, the high barrier film can effectively reduce the thickness of wrapper, helps promoting packing lightweight, thin-walled property.
For many years, development high-barrier compound package material has become a global trend.The high barrier packaging material have all obtained developing rapidly and improving from aspects such as quality, form, function, kinds, and have all obtained using widely in fields such as packaging for foodstuff, medicine packing.
Intercepting the good packaging material of steam performance can be controlled at the moisture in the food in certain scope, can keep original local flavor of food in a long time, can stop that the aqueous vapor of packaging material outside enters in the packaging bag simultaneously again effectively.Because entering of aqueous vapor, help the breeding of bacterium and add rotten (numerous food product need be preserved) of instant food under dry status, this requires packaging material also to have the performance of good obstruct steam simultaneously again in many places, can prevent effectively that airborne steam from entering in the food.
Domestic high barrier material commonly used has:
1. aluminium foil: barrier property is best, but boiling, can effectively intercept ultraviolet ray; But it is opaque, folding resistance is poor, the cost height, can not be used for heating using microwave.
" China's Dairy Industry authority " Luo Cheng professor that itches points out: UHTS milk adopts aseptic bag and Lilezhen packing mostly at present, and the compound packaging material whole nation of this paper aluminium amounted to and consumes 11,000,000,000 approximately in 2004, calculated by each packaging material 10 gram, equaled 110,000 tons.Be difficult for degraded owing to contain metal level (aluminium foil) in these packaging materials; aluminium foil in the composite domestic impotentia is again at present separated; the result causes the discarded object of the composite of the composite of paper constructed of aluminium and plastic-aluminum structure both can't recycling; can't burn again, very harmful to the protection of environment.
2. metallized film: folding resistance is better than aluminium foil, and barrier property can approach aluminium foil, can intercept ultraviolet ray, the low processing cost of aluminizing; That its weak point is is opaque, coating strength is poor (aluminium lamination easily comes off automatically after meeting water), can not be used for heating using microwave.
3. ethylene-vinyl alcohol EVA (EVOH) five-layer co-squeezing film: have excellent barrier property, have good oil resistant and organic solvent resistance, antistatic property, can regeneration, only produce CO during burning
2And H
2O is outstanding environmental protection packaging material; But when ambient humidity surpassed 50%, the rapid variation of its barrier property was so should not use separately.All very expensive because of the investment of import EVOH resin, the multi-layer co-extruded equipment of import, cause product cost very high.
4, polyvinylidene chloride (PVDC) coated film: have the performance of good blocking oxygen and obstruct steam simultaneously, coating is heat sealable, cost is lower; But this film coated needs special equipment, can not the melt pelletization regeneration, and discarded object can produce poisonous to the mankind and surrounding environment, the harmful material of hydrogen chloride, dioxin and so on when burning.
5. performances such as plating silicon oxide film and plating aluminum oxide film: the transparency is good, and resistance oxygen, resistance are wet are very outstanding, but because equipment investment is extremely expensive, process technology is very difficult in addition, so product cost is high.The present domestic production of units that also do not have, also few from the product of external import.
