The utility model is characterized in that the paired recoverable food package bag is composed of an inner and an outer package bags which are combined, the outer package bag is a child-mother mouth aluminium plastic composite bag formed by that a plastic child-mother mouth is arranged on the surface of an inner layer of the position of an opening of an aluminium plastic composite bag by heat seal, the child-mother mouth is composed of a plastic concave edge and a plastic convex edge, the aluminium plastic composite bag is a three-edge sealed bag which is compounded by that an inner and an outer layers are plastic middle layers which are the material of aluminium foil which plays the action of the protection from the light, and the child-mother mouth plays the action of repeated opening and closing. The inner package bag made of transparent plastic which can be made by vacuum heat seal and after the inner package bag is evacuated and sealed with the heat seal, the inner package bag plays the action of sealing.

Description

Food-packing bag

The utility model relates to a kind of food pack, particularly a kind of make food can lucifuge sealing fresh-keeping, the customer can see the packaging bag of the index of qualitys such as shape color and luster of packaging food.

Existing mother-son mouth packaging bag is to blow out tubbing with transparent plastic material by plastic film blowing machine, and thermal cutting is made again, and its defective is that the food of packaging can not reach the fresh-keeping effect of lucifuge sealing.

Usually the lucifuge that solves food seals the packaging bag of fresh-keeping problem, is to adopt the aluminium plastic composite packaging bag, packs with vacuum heat seal wrapping machine, and its shortcoming is the index of qualitys such as shape color and luster that the customer can not see packaging food, does not also know the fine or not true and false of food.

The purpose of this utility model is to provide a kind of improved food pack, and it both can make the sealing of food lucifuge fresh-keeping, can allow the customer see the index of qualitys such as shape color and luster of packaging food again, let alone to choose.

The utility model is achieved in that by inside and outside two packaging bags and finishes.External packing is the mother-son mouth aluminium plastic composite packaging bag that plastics mother-son mouth heat-sealing is made on the internal layer surface of an Aluminum-plastic composite bag opening part, and the plastics mother-son mouth is made up of a plastics concave edge and a plastics chimb, Aluminum-plastic composite bag is to be that plastic interlayer is the compounded three banding sacks of material of aluminium foil by ectonexine, aluminium foil plays the lucifuge effect, and mother-son mouth can close with heavy-handed opening again.Inner packing is that it finds time to seal after the heat seal by the packaging bag that can make with the transparent plastic material that the vacuum heat seal is packed.Food is packed in the clear plastic wrap pack, after finding time to seal with vacuum heat seal wrapping machine, reinstall in the mother-son mouth Aluminum-plastic composite bag, close mother-son mouth with hand and seal.Reach the fresh-keeping effect of lucifuge sealing with regard to the food that makes packaging like this, when the customer buys the food that uses this packing, open mother-son mouth with hand and just can see the index of qualitys such as shape color and luster of food in the packing inside bag, thereby discern its fine or not true and false situation.So neither influence the fresh-keeping effect of food, can recover the shape of original packing again again.

The utility model: because just existing mother-son mouth is heat sealed to the opening part on three banding Aluminum-plastic composite bag internal layer surfaces as external packing, inner packing is by making with the clear plastic wrap pack that the vacuum heat seal is packed, like this, outer packaging bag has solved the not photophobism of existing mother-son mouth packaging bag, packing inside bag has solved existing mother-son mouth packaging bag blowing-by, and the exterior and interior packing engage sleeves needs the fresh-keeping effect of lucifuge sealing with just having reached food.Mother-son mouth can close with heavy-handed opening again, can see the index of qualitys such as shape color and luster of packing inside bag packaging food when the customer buys, and not influence its fresh-keeping effect, can recover the shape of original packing again.

Below with reference to accompanying drawing the utility model is described in further detail.

Fig. 1 is an outer packaging bag scheme drawing of the present utility model.

Fig. 2 is a packing inside bag scheme drawing of the present utility model.

Label among Fig. 1＜1〉is the external packing Aluminum-plastic composite bag, and label＜2〉is the plastics chimbs, and label＜3〉is the plastics concave edges.Label among Fig. 2＜4〉is the inner packing transparent plastic bag.

The utility model is combined by inside and outside two packaging bags.Outer packaging bag is the mother-son mouth Aluminum-plastic composite bag that the mother-son mouth heat-sealing of being made up of a plastics chimb＜2〉and plastics concave edge＜3〉is made on the internal layer surface of an Aluminum-plastic composite bag＜1〉opening part, and aluminium foil plays the lucifuge effect, and mother-son mouth can close with heavy-handed opening again.Inner packing is that it finds time to seal after the heat seal with transparent plastic bag＜4 〉.The customer can see the index of qualitys such as shape color and luster of packaging food.
