Abstract
The packaging material with the fresh-keeping function has the fresh-keeping, air-isolating and light-blocking functions by utilizing the high-isolating function of polybutylene terephthalate compared with the common polyethylene terephthalate to replace the original package. The polybutylene terephthalate high-barrier material can be used for heat sealing the outer layer coated with aluminum oxide and a fresh-keeping layer, so that the polybutylene terephthalate high-barrier material has a fresh-keeping function. The polybutylene terephthalate is used to replace traditional polyethylene terephthalate, and the preservation period is prolonged. Can be widely used for food packaging bags, fruit juice packaging bags, fruit packages, vegetable packages and the like.
Description
Technical field
The present invention relates to a kind of wrapping material, especially a kind of wrapping material of fresh-keeping function.
Background technology
Raising along with the packing safety requirements. the kind of wrapping material is also in variation day by day.Wrapping material must have high barrier, resistance oxygen, moist, the ventilation property of resistance. and high tensile strength, tear-resistant, impact strength, excellent chemical stability also will be arranged, and high thermal resistance satisfies requirements such as the high-temperature sterilization of content and cryopreservation.PBT is one of the most tough and tensile engineering thermoplastic materials, and it is a those semi-crystalline materials, and extraordinary chemical stability, physical strength, electrical insulation characteristics and thermostability are arranged.These materials all have good stability under very wide envrionment conditions.
Summary of the invention
Task of the present invention is: a kind of wrapping material of fresh-keeping function are provided, utilize the more common polyethylene terephthalate of polybutylene terephthalate that the high barrier function is arranged, replace original packing with it, have more fresh-keeping trapping resistance light action.
The technology of the present invention is constructed as follows:
The wrapping material of fresh-keeping function are coated with aluminum oxide and fresh-keeping layer with the heat sealable skin of polybutylene terephthalate high barrier material, make it have fresh-keeping function.
With respect to original technical progress effect be like this: after replacing traditional polyethylene terephthalate with polybutylene terephthalate, fresh-keeping cycle stretch-out.
Embodiment
In specific implementation process, utilize the more common polyethylene terephthalate of polybutylene terephthalate that the high barrier function is arranged, replace original packing with it, have more fresh-keeping trapping resistance light action.Can be widely used in food pack, juice packages bag, fruit packaging, vegetables packing etc.
Claims (1)
1. the wrapping material of fresh-keeping function is characterized in that being coated with aluminum oxide and fresh-keeping layer is made with the heat sealable skin of polybutylene terephthalate high barrier material.
