Abstract
The utility model discloses a polyethylene film packaging structure, which is used for packaging structure heat sealing layers and can realize boiling sterilization without vacuuming. The polyethylene film packaging structure comprises at least a metallocene polyethylene film layer and at least an auxiliary film layer which are stacked together. The metallocene polyethylene film can bear the temperature between -30 DEG C and 110 DEG C and simultaneously has strong tensile strength and crack resistance, the composite product can be put into water for boiling sterilization without vacuuming, and layering and bag blasting of the packaging structure can not be caused. The transparent auxiliary film layer can be made of polyethylene with lower price, so the production cost is reduced, and the structure is especially suitable for packaging various products such as noodles, edible fungi and the like which are deformed easily due to extrusion.
Description
Technical field
The utility model relates to packaging structure, is specifically related to a kind of polyethylene foil packaging structure that is used for the packaging structure hot sealing layer.
Background technology
Existing poach packaging structure generally comprises and is positioned at exterior printed layers and is positioned at the in-to-in hot sealing layer, and hot sealing layer generally adopts polyethylene foil to make.The joint product of traditional polyethylene foil all needs packaging structure is carried out the poach sterilization after packed article is packed, but water temperature after boiling reaches 100 ℃, and can cause that the packaging structure gas inside expands.Therefore, existing polyethylene foil joint product all need vacuumize processing before the poach sterilization, otherwise causes the layering of packaging structure, quick-fried bag easily; And can not bear and surpass 100 ℃ sterilization mode, if surpass 100 ℃, cause easily polyethylene foil self adhesion or with the adhesion of packed article.
The utility model content
The technical matters that the utility model solved provides a kind of polyethylene foil packaging structure that carries out the poach sterilization under situation about not vacuumizing.
The technical scheme that its technical matters that solves the utility model adopts is: the polyethylene foil packaging structure comprises the metallocene polyethylene film layer of one deck at least stacked together and one deck supporting film layer at least.
Further be that described metallocene polyethylene film layer and supporting film layer are hyaline layer.
Further be, described metallocene polyethylene film layer and supporting film layer have three layers, are respectively internal layer, middle level and skin, and wherein internal layer is the metallocene polyethylene film layer, and the middle level is the supporting film layer with skin.
The beneficial effects of the utility model are: metallocene polyethylene film can bear the range of temperatures between-30 ℃ to 110 ℃, simultaneously, have very strong tension and cracking resistance characteristic, this composite article can be transferred in the situation that does not vacuumize processing and be carried out the poach sterilization processing in the entry, and can not cause the layering and the quick-fried bag of packaging structure.And transparent supporting film layer can adopt the lower polyethylene of some prices to make, and manufactures cost thereby reduce, and is particluarly suitable for various noodles, edible fungi etc. and promotes the use of above the packing of the product of extrusion easily.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Be labeled as among the figure: internal layer 1, middle level 2, outer 3.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, polyethylene foil packaging structure of the present utility model comprises the metallocene polyethylene film layer of one deck at least stacked together and one deck supporting film layer at least.Metallocene polyethylene film is the normal membraneous material that adopts of chemical field, promptly be the synthetic polyethylene foil of catalyst with the metallocene, and metallocene catalyst is meant the catalyst system and catalyzing of being made up of metallocene major catalyst and lewis acid catalyst-accelerator.When moulding, metallocene polyethylene film layer and supporting film layer form by blown film.This metallocene polyethylene film can bear the range of temperatures between-30 ℃ to 110 ℃, therefore can bear the poach temperature more than 100 ℃, simultaneously, have very strong tension and cracking resistance characteristic, then after the composite article packaging structure of the utility model polyethylene foil packages packed article, can vacuumize processing and can put into water and carry out the poach sterilization processing, and can not cause the layering and the quick-fried bag of packaging structure.And transparent supporting film layer can adopt the lower polyethylene of some prices to make.In this embodiment, for ease of seeing the packing material in the packaging structure, described metallocene polyethylene film layer and supporting film layer are hyaline layer.
In the above-described embodiment, the metallocene polyethylene film layer can be arranged on skin, also can be arranged on internal layer, as optimal way, described metallocene polyethylene film layer and supporting film layer have three layers, be respectively internal layer 1, middle level 2 and skin 3, wherein internal layer 1 is the metallocene polyethylene film layer, and middle level 2 is the supporting film layer with outer 3.The metallocene polyethylene film layer is set to internal layer 1, can improve the heat resistance of the utility model polyethylene foil packaging structure, prevents that material and the packed article in the internal layer 1 from sticking together in the poach process.And middle level 2 can farthest reduce with outer 3 supporting film layer and manufactures cost, simultaneously the metallocene polyethylene film layer in the internal layer 1 is played protection and reinforcement effect.
Claims (3)
1. polyethylene foil packaging structure is characterized in that: comprise the metallocene polyethylene film layer of one deck at least stacked together and one deck supporting film layer at least.
2. polyethylene foil packaging structure as claimed in claim 1 is characterized in that: described metallocene polyethylene film layer and supporting film layer are hyaline layer.
3. polyethylene foil packaging structure as claimed in claim 1 or 2, it is characterized in that: described metallocene polyethylene film layer and supporting film layer have three layers, be respectively internal layer (1), middle level (2) and outer (3), wherein internal layer (1) is the metallocene polyethylene film layer, and middle level (2) are the supporting film layer with outer (3).
