Description
Technical field
The invention belongs to technology field of membrane materials, are specifically related to a kind of two-sided heat-sealing high-barrier high transparency aluminium oxide PET
Film and preparation method thereof.
Background technique
With the improvement of economic condition and the raising of people's quality of the life, consumer also gets over the safety of food with nutrition
More to pay close attention to.And most of food is easy the pollution by moisture, oxygen, microorganism in environment etc. and occur quality decline and
It is rotten, therefore the high resistant barrier food package that can play barrier vapor, oxygen etc. is developed rapidly and is widely applied in recent years.
The barrier property of packaging material refers to the performance that material prevents small molecule from penetrating, and small molecule therein includes moisture
Son, O2、N2、CO2And the gas molecules such as organic gas, both included that barrier ambient atmos enter package interior, and had also included preventing packet
Moisture, fragrance inside dress etc. are permeable.For example, food packaging is the important component of food, it both protects food, makes
Food prevents biology in the process of circulation in the hand for leaving factory arrival consumer, physics, chemical foeign element
Damage also has the function of keeping food quality stable, the use of instant food, while attracting consumer further through appearance, has
An important factor for value other than material cost, the barrier property of food packaging is the superiority and inferiority of influence food packaging, food packaging
Barrier property is determined by the self character of food, and requirement of the different food to barrier property is also each different, food packaging
On the one hand barrier property guarantees extraneous bacterium, dust, light, particulate matter, moisture cannot enter in food, in addition in guarantee food
Moisture, grease, aroma ingredients do not flow out in outside air, to achieve the purpose that food never degenerates.
Different packaging materials is formed by different monomer polymerizations, the molecular size range of main polymer chain, side chain machine group
Combination, microstructure is different, cause material in density, crystallinity, hardness, mechanical strength, the difference in heat sealability, thus
So that different materials, to vapor, oxygen, the substances such as fragrance have the performance of different barrier properties.
Chewing gum currently on the market, chocolate, haw flakes are all using transparent Double-side hot in the outer packings such as saqima
The KBOPP film of envelope, two-sided heat-sealing can seal envelope and wrap up product, transparent effect can make in packaging process
Consumer sees content, while KBOPP has certain barrier property again, and the food such as protection chewing gum never degenerate, but KBOPP
Barrier property be limited, the quality of food product inside can not be maintained for a long time, this shelf-life for allowing for product falls short of,
And there is rotten risks.A kind of two-sided heat-sealing is researched and developed, high-barrier, high transparency film is for chewing gum, chocolate, hawthorn
Piece, the packaging material important in inhibiting of the food such as saqima, can protect internal product not to be contaminated, and have at the same time more
Excellent barrier property is able to extend the shelf life of entire product, there is higher transparency, the displaying product that can be more clear
Appearance, have great significance to such food packaging.
