Abstract
A puncture-resistant high-barrier fresh-keeping packaging bag. The problem of the new freshness of packing material is influenced in order to solve present freshness package puncture resistance can be poor, often can lead to in the process damage such as transportation, simultaneously to the barrier properties of oxygen and vapor poor, can lead to the oxygen content increase in the packing after long-time transportation. The utility model discloses a PE layer (5), deoxidation consumption layer (4) and high barrier layer (2), deoxidation consumption layer coat in PE layer on, deoxidation consumption layer on bond through glue and have toughening layer (6), toughening layer on bond through glue and have high barrier layer, high barrier layer on bond and have outer PA layer (1). The utility model is suitable for a what pack hinders oxygen, hinders wet, deoxidization, increases tough.
Description
Technical Field
The utility model relates to a puncture-resistant high resistant separates fresh-keeping wrapping bag.
Background
Most rice class and the miscellaneous cereals class of market sell the product at present, all use the evacuation product as the owner, and the product form has certain influence to packing destructiveness, and present freshness protection package puncture resistance is poor, often can lead to in the process damage such as transportation, simultaneously to the barrier property difference of oxygen and vapor, can lead to the oxygen content increase in the packing after long-time transportation, influences the new freshness of packing material.
Disclosure of Invention
The utility model discloses a solve present freshness protection package puncture resistance can be poor, often can lead to in-process damage such as transportation, simultaneously to oxygen and vapor's separation performance poor, can lead to the oxygen content in the packing to increase after long-time transportation, influence the fresh problem of degree of packing, provide a puncture-resistant, hinder oxygen, deoxidation effect's puncture-resistant high separation freshness protection package.
The above purpose is achieved by the following scheme:
the utility model provides a puncture-resistant high resistant separates fresh-keeping wrapping bag, a puncture-resistant high resistant separates fresh-keeping wrapping bag include PE layer, deoxidation consumption layer and high barrier layer, deoxidation consumption layer coat in PE layer on, deoxidation consumption layer on have the layer of toughening through glue bonding, the layer of toughening on bond through glue and have high barrier layer, high barrier layer on bond and have outer PA layer.
The puncture-resistant high-barrier fresh-keeping packaging bag is characterized in that the deoxidation consumption layer is an ascorbic acid layer, and the high-barrier layer is a PVA (polyvinyl alcohol) primer glue layer.
The puncture-resistant high-barrier fresh-keeping packaging bag is characterized in that the toughening layer is a PA layer.
Advantageous effects
1. The utility model discloses a compound on two PA layers, outer PA layer transparency is good, has good glossiness, and tensile strength, tensile strength are higher, have better heat resistance, cold resistance, and wearability, puncture resistance are good, and softer relatively, hinder oxygen performance good, and inlayer PA layer is for toughening the layer, increases the puncture resistance of packing.
2. The utility model discloses a high barrier layer is PVA first coat glue, its composition polyvinyl alcohol, the light fastness is good, does not receive the illumination influence, has very powerful separation nature to oxygen and vapor, its oxygen permeability < 0.5 cm/(m 24h 0.1 MPa), vapor permeability < 5g (square meter 24 h).
3. The utility model discloses a deoxidation consumption layer is ascorbic acid layer for after the product evacuation, sustainable have the deoxidation effect, can be with the residual gas desorption in the packing.
Drawings
FIG. 1 is a schematic structural view of the present invention;
in the figure: 1. an outer PA layer; 2. a high barrier layer; 3. glue; 4. a deoxidation depleted layer; 5. a PE layer; 6. and a toughening layer.
The specific implementation mode is as follows:
in order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, the puncture-resistant high-barrier fresh-keeping packaging bag comprises a PE layer 5, a deoxidation consuming layer 4 and a high barrier layer 2, wherein the deoxidation consuming layer is coated on the PE layer, and a thermoplastic high polymer formed by polymerizing ethylene has good mechanical strength, dielectric property and moisture resistance, can keep flexibility and stability at low temperature, does not react with moisture, grease, compounds and the like, can bear the low temperature of-70 ℃, and has heat sealing property; the deoxidation consumption layer is an ascorbic acid layer, so that the product can continuously have deoxidation effect after being vacuumized, and residual gas in the package can be removed;
the deoxidation consumption layer is bonded with a toughening layer 6 through glue 3, the toughening layer is a PA layer, and the puncture resistance of the package is improved;
the high barrier layer is adhered to the toughening layer through glue, is a PVA (polyvinyl alcohol) -based priming glue layer, is polyvinyl alcohol and has good light resistance, is not influenced by illumination, has very strong barrier property on oxygen and water vapor, and has oxygen transmission amount smaller than 0.5cm (m.24 h.0.1 MPa) and water vapor transmission amount smaller than 5g (square meter.24 h);
the main component of the glue is polyurethane, each layer of plastic film has a bonding effect, the main chain of the glue is very flexible, the glue can resist impact vibration and bending fatigue, the peeling strength can reach more than 3N, and the glue has excellent low-temperature resistance;
the outer PA layer 1 is bonded on the high barrier layer, is a tough film, has good transparency, good glossiness, high tensile strength and tensile strength, good heat resistance and cold resistance, excellent wear resistance and puncture resistance, softness and good oxygen barrier property.
This composite packaging has extremely strong separation nature to oxygen and vapor to have the deoxidation effect, but oxygen content in the simultaneous control packing material, to selling the area not limitation, can unlimited enlarge the sales radius, new freshness all can be guaranteed to high temperature, high humidity, do not influence the quality because of the environment, can prolong product shelf life and new freshness, each item performance index of this packing is as follows:
the above description is intended to be illustrative of the preferred embodiment of the present invention and should not be taken as limiting the invention, but rather, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.
