Description
Technical field
The present invention relates to packaging material for food application, particularly relate to a kind of degradable antibacterial food package film.
Background technology
Packaging for foodstuff is last procedure of modern food industry, and it plays protection, publicity and instant food storage, fortune
Important function defeated, that sell, has become as the important component part that food is indispensable.Along with the circulation of food expands to
All over the world, not only need the shelf life that food maintenance is longer, the quality that nutrition to be kept is fresh, there is specific function
Active packing just arises at the historic moment.And antimicrobial packaging is most important one in active packing, obtains people and paid much attention to and wide
General research, suppresses the growth of food microorganisms in storage and avoids the secondary pollution of food, thus extending the guarantor of food
The matter phase.
Plastics package is the emerging packaging material that recent decades grows up, and is widely used in all kinds of product with its excellent performance
In product.But plastic package material belongs to high molecular synthetic material, mostly enter municipal solid wastes after using and enter rubbish
Processing system, or arbitrarily abandon, become " white pollution ".The ratio maximum that plastic package material is shared in garbage, its
The pollution being caused environment is also the most serious in each based packaging material.
Thus, it is necessary to provide a kind of environmentally friendly, degradable, there is the food package film of antibiotic property, a side
Food can be played the effect of durable antibiotic by face, on the other hand can degrade after a procedure, alleviates the pollution to environment.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of degradable antibacterial food package film, extending
While effective period of food quality, additionally it is possible to carry out degradable by light or organisms, environmental protection completely after discarded.
For achieving the above object, the technical scheme that the present invention takes is as follows:
A kind of degradable antibacterial food package film, for layer structure, ecto-entad is followed successively by protective clear layer (1), printing layer
(2), printing element layer (3), degradable barrier layer (4) and biodegradable antibacterial hot sealing layer (5), described transparency and heat-proof guarantor
Being added with photosensitizer in sheath (1) and printing element layer (3), described degradable barrier layer (4) is by the list containing photosensitive group
Body is made with olefin monomer copolymerization, and described biodegradable antibacterial hot sealing layer (5) is by the aliphatic polyester containing ester group structure
Make, described biodegradable antibacterial hot sealing layer (5) is added with antibacterial, described degradable antibacterial food package film phase
By being hot bonding between adjacent bed.
Preferential, described protective clear layer (1) is polyolefin.
Preferential, described printing element layer (3) is two-way stretching polyamide, Biaxially oriented polypropylene or poly-terephthaldehyde
Acid glycol ester.
Preferential, in described transparency and heat-proof protective layer (1) and printing element layer (3), photosensitizer is benzophenone, two cyclopentadienyls
Ferrum, ferric stearate or alkylthio carbamic acid ferrum.
Preferential, the described monomer containing photosensitive group in degradable barrier layer (4) is ethylene methacrylic ketone, methyl
Propenone or vinyl alcohol cinnamate.
Preferential, the described olefin monomer in degradable barrier layer (4) is ethylene or propylene.
Preferential, the described aliphatic polyester containing ester group structure in biodegradable antibacterial hot sealing layer (5) is poly-breast
Acid, polycaprolactone or polyesteramide.
Preferential, the antibacterial added in described biodegradable antibacterial hot sealing layer (5) is vanillin or ethyl vanillin
Aldehyde.
Preferential, the thickness of described protective clear layer (1) be 10-20 micron, the thickness of printing element layer (3) be 20-
30 microns, the thickness of degradable barrier layer (4) be 20-30 micron, the thickness of biodegradable antibacterial hot sealing layer (5) be 20-
30 microns.
Beneficial effects of the present invention is as follows:
The agent structure of the most degradable barrier layer (4) is to introduce photosensitive group by copolymerized form, it is to avoid little molecular photoactive
The use of agent, on the one hand improves packaging film strength, also prevents in protective clear layer (1) and printing element layer (3) simultaneously
Photosensitizer is to the migration of inner side.
The most biodegradable antibacterial hot sealing layer (5) is made up of the aliphatic polyester containing ester group structure, and ester group structure is in micro-life
Can carry out biodegradation under substance environment, and polymer of such synthesis can overcome and becomes packaging film by pure natural Process Technology of Polymer
Time the shortcoming such as difficult, the film properties difference of processing technique.
3, biodegradable antibacterial hot sealing layer (5) is added with antibacterial, after using antibiotic packaging material, food processing
Production process just need not add as conventional procedure substantial amounts of preservative, effectively prevent the Excess free enthalpy of preservative, increase
Add the safety of food.
By thermo-compression bonding between each layer of the most double down solution hot-fill food packaging film, do not use binding agent, it is possible to reach food
The safety and health request of product packaging bag, each layer of food package film all can be degraded simultaneously, fully meets environmental requirement.
