Description
Technical Field
The utility model relates to a stratiform product, concretely relates to hot-seal chafing dish bed charge shaping membrane of antipollution.
Background
When the hotpot condiment is packaged by a plastic container, a forming film is generally required to seal an opening of the plastic container. However, because a large amount of oil substances exist in the hotpot condiment, if the oil substances pollute the surface of the forming film, the heat sealing strength of the forming film is low, and the air leakage rate of a packaged product is high (generally about 12 percent); in order to ensure the air tightness of products after packaging, the hotpot condiment is generally placed by someone during packaging at present, and special personnel wipe the contaminated forming film area at the back, so that the time and labor are wasted, the packaging efficiency is reduced, the labor is wasted, and the labor cost is high.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a hot pot seasoning shaping film of antipollution heat-seal is provided, this kind of hot pot seasoning shaping film still can have good heat sealability under the circumstances of being polluted by the greasy dirt, is favorable to guaranteeing the gas tightness of packing back goods. The technical scheme is as follows:
the utility model provides a hot pot seasoning shaping film of antipollution heat-seal, includes first nylon layer, polyethylene layer and heat-seal layer, its characterized in that: the heat-sealing adhesive tape further comprises a second nylon layer, a first adhesive layer and a second adhesive layer, wherein the first nylon layer, the first adhesive layer, the second nylon layer, the second adhesive layer, the polyethylene layer and the heat-sealing layer are sequentially arranged from outside to inside; the heat sealing layer is a sarin layer, and the second nylon layer is made of copolymerized nylon.
In the hot pot seasoning forming film, the first nylon layer can provide barrier property, outer layer gloss, surface layer temperature resistance and easy forming property for the forming film, the barrier property of nylon is utilized to improve the pollution resistance of the forming film, and good help is provided for the air tightness of a packaged product; the polyethylene layer can provide good toughness for the formed film; the second nylon layer is made of copolymerized nylon, so that on one hand, good barrier property can be provided for hotpot condiment products, on the other hand, more excellent stretch forming performance is provided, and the lowest point thickness of a forming film is ensured; the first bonding layer is used for bonding the first nylon layer and the second nylon layer together and ensuring certain bonding strength; the second bonding layer is used for bonding the second nylon layer and the polyethylene layer together and ensuring certain bonding strength; the heat-sealing layer is a sand forest layer, the pollution-resistant heat-sealing performance of the sand forest is utilized, the forming film can have good heat-sealing performance under the condition of being polluted by oil dirt, and the air tightness of the packaged product is guaranteed.
The surlyn layer may be made of ionic polymer surlyn manufactured by dupont materials.
In a preferred embodiment, the polyethylene layer includes a first polyethylene sublayer and a second polyethylene sublayer, the outer surface of the first polyethylene sublayer is bonded to the second nylon layer through the second adhesive layer, and the second polyethylene sublayer is disposed between the first polyethylene sublayer and the heat seal layer.
In a more preferable embodiment, the first polyethylene sublayer and the second polyethylene sublayer are both formed by mixing metallocene PE and linear low density polyethylene. Thus, the molded film can have excellent toughness.
In a preferred embodiment, the first nylon layer is made of homopolymeric nylon. Therefore, the first nylon layer can provide good barrier property, outer layer gloss, surface layer temperature resistance and easy forming property for the forming film, and provides good help for the air tightness of the packaged product.
Preferably, the first adhesive layer and the second adhesive layer are made of an adhesive. The adhesive is PE-based adhesive, so that the adhesion between different layers of the formed film can be ensured, and a certain adhesive strength is ensured.
Generally, the hot pot seasoning forming film is produced by a down-blowing water cooling process, the temperature of cooling water is 10 ℃, and the film is rapidly cooled, so that the crystallinity of the film is reduced, the transparency of the film is improved, and the low crystallinity ensures the forming performance of the film.
The second nylon layer is arranged between the first nylon layer and the polyethylene layer, so that the hot pot seasoning forming film can provide very good barrier property and more excellent stretch forming performance for hot pot seasoning products, and the heat sealing layer is a sand forest layer, so that the anti-pollution heat sealing performance of the sand forest is utilized, and the forming film can have good heat sealing performance under the condition of being polluted by oil dirt; therefore, the anti-pollution capacity of the hot pot seasoning forming film is high, the hot sealing performance can be good even if the hot pot seasoning forming film is polluted by oil dirt, the condition that the hot pot seasoning is cleaned in a manual mode like the prior art can be avoided, the air tightness of packaged products is guaranteed, and the packaging efficiency is improved.
