Abstract
The utility model is related to Food Packaging technology fields, a kind of sealing film is disclosed, including biaxial stretching polyester layer (1), linear low density polyethylene (LLDPE) corona layer (2), acrylic resin and vinyl acetate resin adhesive layer (3), low density polyethylene (LDPE), metallocene linear-low density polyethylene and the linear low density polyethylene hot sealing layer (4) and antibiotic layer (5) contacted successively.The acrylic resin and vinyl acetate resin adhesive layer (2) of the utility model have good flexibility and cohesive force, sealing can be repeated several times with low density polyethylene (LDPE), metallocene linear-low density polyethylene and linear low density polyethylene hot sealing layer (3) in it, there is the adhesive layer preferable bonding force, realization to seal function again；In addition, the sealing film is equipped with antibiotic layer, it can effectively extend shelf life of products using more convenient with direct food contact, it is safer.
Description
Technical field
The utility model is related to Food Packaging technology fields, more particularly to a kind of sealing film.
Background technology
Traditional polyethylene sealing film is sealed with food packaging container (such as PET pallets, PP bowl), can not be again after opening
Secondary sealing (such as weight pressure, clip) need to be such that it is bonded again bulk goods by other means, play protection food
The effect of product.
Packaging can be sealed again in the market and mostly use liquid pressure sensitive type adhesive as raw material is sealed again, pass through professional application type
Equipment is coated on film and realizes and seal function again, but such film cannot be with direct food contact.
Utility model content
The shortcomings that the utility model cannot seal again for polyethylene film traditional in the prior art, provides one kind
Seal film, which can effectively extend shelf life of products using more convenient with direct food contact, safer.
In order to solve the above-mentioned technical problem, the utility model is addressed by following technical proposals：
A kind of sealing film, including the biaxial stretching polyester layer, linear low density polyethylene corona layer, the acrylic acid that contact successively
Resin and vinyl acetate resin adhesive layer, low density polyethylene (LDPE), metallocene linear-low density polyethylene and linear low density polyethylene
Alkene hot sealing layer and antibiotic layer.
Preferably, biaxial stretching polyester layer, linear low density polyethylene corona layer, acrylic resin and vinyl acetate tree
Fat adhesive layer, low density polyethylene (LDPE), metallocene linear-low density polyethylene and linear low density polyethylene hot sealing layer and antibacterial
The thickness ratio of layer is 2~3:1.5~2.5:1~2:1~3:0.5~1.
Preferably, the thickness of sealing film is 30~115 μm.
The utility model has significant technique effect as a result of above technical scheme：The propylene of the utility model
Acid resin and vinyl acetate resin adhesive layer have good flexibility and cohesive force, with low density polyethylene (LDPE), metallocene line
Property low density polyethylene (LDPE) and linear low density polyethylene hot sealing layer sealing can be repeated several times, which has preferable bonding
Power, realization seal function again.It, can be effective using more convenient with direct food contact in addition, the sealing film is equipped with antibiotic layer
Extend shelf life of products, it is safer.
Description of the drawings
Structural schematic diagram when Fig. 1 is the utility model sealing.
Fig. 2 is structural schematic diagram when the utility model is opened.
The toponym that each number designation is referred in the figures above is as follows：Wherein, 1-biaxial stretching polyester layer, 2-lines
