Abstract
A novel high strength packaging film of preservative belongs to the technical field of packaging films. The outer layer is a plastic film layer, and the inner layer is an air permeation film layer. A non-woven fabric layer is arranged between the plastic film layer and the air permeation film layer in matching mode. The non-woven fabric layer and the plastic film layer are bonded and compounded through a first bonding layer. The non-woven fabric layer and the air permeation film layer are bonded and compounded through a second bonding layer. The novel high strength packaging film of preservative is simple in structure and reasonable in design. The polyethylene (PE) net in the prior packaging film is replaced by the non-woven fabric. The packaging film adopting the structure can reduce power leakage rate and production cost. The packaging film has high tearing strength and good air permeability.
Description
Technical field
The utility model belongs to the packaging film technical field, is specifically related to a kind of novel 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 novel high-strength antistaling agent packaging film is provided.
Described a kind of novel high-strength antistaling agent packaging film; Skin is a plastic membranous layer; Internal layer is ventilative rete; It is characterized in that being equipped with nonwoven layer between described plastic membranous layer and the ventilative rete, gluing compound between described nonwoven layer and the plastic membranous layer through first tack coat, gluing compound between described nonwoven layer and the ventilative rete through second tack coat.
Described a kind of novel high-strength antistaling agent packaging film is characterized in that described plastic membranous layer is OPP plastic membranous layer, PET plastic membranous layer or NY plastic membranous layer.
Described a kind of novel high-strength antistaling agent packaging film is characterized in that described plastic membranous layer is provided with air-vent, and described air-vent aperture is 0.2～2mm.
Described a kind of novel high-strength antistaling agent packaging film, the thickness that it is characterized in that described plastic membranous layer is 10～30mm.
Described a kind of novel high-strength antistaling agent packaging film is characterized in that described first tack coat is tackifying resin tack coat, polyurethane adhesive or water-based glue tack coat.
Described a kind of novel high-strength antistaling agent packaging film is characterized in that described nonwoven layer is PET nonwoven layer or PP nonwoven layer.
Described a kind of novel high-strength antistaling agent packaging film, the weight that it is characterized in that described nonwoven layer is 20g/m

Described a kind of novel high-strength antistaling agent packaging film is characterized in that described second tack coat is tackifying resin tack coat, polyurethane adhesive or water-based glue tack coat.
Described a kind of novel high-strength antistaling agent packaging film is characterized in that described ventilative rete is ventilative rete of CPP or the ventilative rete of CPE.
Described a kind of novel high-strength antistaling agent packaging film is characterized in that on the described ventilative rete micropore being set, and described micropore size is 0.2～2mm.
Above-mentioned a kind of novel high-strength antistaling agent packaging film; Simple in structure, reasonable in design, the PE net in original packaging film is replaced with nonwoven layer; Adopt the packaging film of said structure both can reduce the probability that leaks powder; Can reduce production costs again, and this packaging film has higher tearing strength, the high ventilation performance.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: the 1-plastic membranous layer; The 101-air-vent; 2-first tack coat; The 3-nonwoven layer; 4-second tack coat; The 5-rete of breathing freely; The 501-micropore.
The specific embodiment
Further specify the utility model below in conjunction with Figure of description.
As shown in the figure; A kind of novel high-strength antistaling agent packaging film skin is a plastic membranous layer 1; Internal layer is ventilative rete 5; Be equipped with nonwoven layer 3 between plastic membranous layer 1 and the transparent film layer 5, gluing compound between nonwoven layer 3 and the plastic membranous layer 1 through first tack coat 2, gluing compound between nonwoven layer 3 and the ventilative rete 5 through second tack coat 4.
Plastic membranous layer 1 is processed by OPP (o-phenyl phenol) plastic membranous layer, NY (nylon) plastic membranous layer or PET (polyester) plastic membranous layer etc.; Its thickness is 10～30um; Can print on the plastic membranous layer 1, air-vent 101 is set on it, air-vent 101 apertures are 0.2～2mm.First tack coat 2 is tackifying resin tack coat, polyurethane adhesive or water-based glue tack coat, and it can process tackifying resin with EAA, EVA, PE or PP, and its thickness is 2～30um.Nonwoven layer 3 is PET nonwoven layer or PP nonwoven layer, and the weight of this layer is 20g/m
