Description
Technical field
The utility model is related to a kind of plastics aseptic packaging paper and packing box.
Background technology
Tetrapack company of Sweden and Kang Mei companies of Switzerland production for holding neutral liquid plus particle or solid-state tinned food
Paper plastic-aluminum aseptic packaging box, generally include 8 layers, structure composite layer successively using PP layers ply of board PE layers EAA layers aluminium foil
Layer EAA layers PE layers PP layers.But, because containing paper sheet in the packing box structure, it is impossible to carry out high-temperature water boil it is sterilized (for example,
121 DEG C of cooking disinfections of water-bath) or spray sterilization, 121 DEG C of wet sterilizations can only be carried out, and wet sterilization can not be usually reached to food
Product are thoroughly sterilized to commercial sterilization.Meanwhile, due also in wet sterilization, compressed air and the positive and negative pressure-volume of high-temperature steam are easily formed
Dead angle, it is impossible to kill the Bacillus in food, causes food qualification rate to can only achieve 98%.Further, since ply of board have every
Thermal effect and steam heat transfer is slow, so as to cause carton centers temperature during wet sterilization unstable, food security it cannot be guaranteed that.And
And, the tinned food wet sterilization time that general paper plastic-aluminum sterility is contained is long, needs 120~150min (wherein, intensification 30min
Left and right, is incubated 60~70min, 30~50min of cooling down), easily there is water penetration in the paper in paper plastic-aluminum aseptic packaging box.
At present, in the market can 121 DEG C of packagings of the vegetable protein liquid beverage of boiling high temperature sterilization frequently with iron flask or aluminium
Tank, can 121 DEG C of packagings of boiling high temperature sterilization solid-state food can frequently with iron flask and vial, however, iron flask or aluminium pot are rich
Containing heavy metal, easily caused damage to healthy；Vial is broken, and security is low for consumer；And, above-mentioned iron
The packaging such as tank, aluminium pot and vial is heavier, also there is the defects such as cost of transportation is high.Those problems demands are solved.
Additionally, acidic beverages of the acidity in pH value below 4.6, plus the acidic beverages or acid canned food of particle do not contain
Bacillus, comprise only general miscellaneous bacteria, therefore (sterilization temperature is at 85~90 DEG C) by pasteurize are only needed in preparation process.Pasteur kills
The mode of bacterium is divided to two kinds：Plus the acidic beverages or canned pack of particle are sterilized using immersion method, agranular acidic beverages are used
Board-like sterilization machine is sterilized.At present, for above-mentioned acidic products, its packaging generally using vial, plastic bottle, plastics butt-ended bag,
The form such as plastic cup or plastic bowl, but because vial is broken, security is low for consumer；Plastics butt-ended bag, modeling
The packaging such as material cup or plastic bowl exists squashy, is easily deformed, and intercepts the defects such as oxygen permeability difference.Those problems demands are solved.
Utility model content
Technical problem to be solved in the utility model is to overcome in the prior art that paper plastic-aluminum aseptic packaging box can not
Carry out high-temperature water to boil, spray sterilized and Pasteur's water dip sterilization, wet sterilization can only be carried out, thus cause sterilized not thorough, food
Qualification rate can only achieve 98%, heat transfer is slow, long sterilizing time, yield poorly, the easy water penetration of paper of packing box, the shelf-life of food
Short and vial fear of throwing, heavier, spraying high temperature boiling is dangerous to food in iron pipe, plastic products are squashy, be easily deformed and
Intercept the defects such as oxygen permeability difference, there is provided a kind of plastics aseptic packaging paper and packing box.Plastics aseptic packaging of the present utility model
Box can not only carry out wet sterilization, can also carry out high-temperature water and boil, spray sterilized (digestion resistant) or pasteurize；Temperature is equal
Even, sterilization process is without dead angle, more thorough, it is ensured that the safety of product 100%, so that food can long term storage；Sterilization process
Middle heat transfer rate is fast, and sterilizing time is short, and packing box is also less prone to water penetration；Its inwall can add plasticiser, heavy metal free unit
Element, during for the acidic beverages, tinned fruit or the solid-state food that hold vegetable protein liquid beverage or the scope of pH value 3~4.6, modeling
Material aseptic packaging box is transparent, lightweight, it can be seen that food in box, more attractive in appearance, safety, health, environmental protection, cost of transportation compared with
It is low.
