Abstract
The utility model relates to a high-strength preservative packaging film, belonging to the technical field of packaging films. The high-strength preservative packaging film comprises an air-permeable film layer. A heat-sealable air-permeable film layer is arranged on the lower surface of the air-permeable film layer through hot pressing or dry combination. The high-strength preservative packaging film has the advantages that the structure is simple, the design is reasonable, not only can the probability of powder leakage be decreased, but also the production cost can be reduced, the tearing strength is higher, the performance is good, the surface is compact and smooth and the printed words are clear.
Description
Technical field
The utility model belongs to the packaging film technical field, is specifically related to a kind of high strength antistaling agent packaging film.
Background technology
Food preservative is meant and is used for preventing that food is in storage, the process of circulation; Because it is rotten that steam, microbial reproduction cause; Or owing to the storage sales terms are not good at; The food interior quality takes place that bad change, color and luster descend, moist deliquescing, is to improve storage life, prolongs edibility and the additive that in food, uses.
Traditional antistaling agent packaging film is provided with the PE net usually between plastic membranous layer and ventilative rete, adopt the packaging film of above-mentioned structure to have the hidden danger of leaking powder usually, and insufficient strength is high, and is influential to food security, and this type of packaging film cost is high.
The utility model content
To the problem that prior art exists, the purpose of the utility model is to design the technical scheme that a kind of high strength antistaling agent packaging film is provided.
Described a kind of high strength antistaling agent packaging film is characterized in that comprising ventilative rete, and described ventilative rete lower surface hot pressing or dry type be compound to be provided with heat sealable ventilative rete.
Described a kind of high strength antistaling agent packaging film is characterized in that described ventilative rete is smooth PET nonwoven layer of single face or the smooth OPP nonwoven layer of single face.
Described a kind of high strength antistaling agent packaging film is characterized in that described ventilated membrane layer thickness is 10～100um.
Described a kind of high strength antistaling agent packaging film is characterized in that described heat sealable ventilative rete is ventilative PE rete, ventilative PP rete or ventilative co-extrusion rete.
Described a kind of high strength antistaling agent packaging film is characterized in that on the described heat sealable ventilative rete micropore being set, and the aperture of described micropore is 0.2～2mm.
Above-mentioned a kind of high strength antistaling agent packaging film, simple in structure, reasonable in design, can reduce the probability that leaks powder, can reduce production costs again, and this packaging film has higher tearing strength, performance is good, surface compact is smooth, and it is clear to print.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: the 1-rete of breathing freely; The heat sealable ventilative rete of 2-; The 201-micropore.
The specific embodiment
Further specify the utility model below in conjunction with Figure of description.
As shown in the figure, a kind of high strength antistaling agent packaging film comprises ventilative rete 1 and heat sealable ventilative rete 2, and ventilative rete 1 is in the same place through hot pressing or dry type compoiste adhering with heat sealable ventilative rete 2.Wherein ventilative rete 1 be smooth PET nonwoven layer of single face or the smooth OPP nonwoven layer of single face, and its thickness is 10～100um, and ventilative rete 1 is surperficial dense smooth, does not leak powder, and print clear; Heat sealable ventilative rete 2 which is provided with micropore 201 for ventilative PE rete, ventilative PP rete or ventilative co-extrusion rete, and the aperture of micropore 201 is 0.2～2mm, and permeability is good.
Shown in the above and the figure only is the preferred implementation of the utility model.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model principle, can also make some modification and improvement, these also should be regarded as belonging to the protection domain of the utility model.
