A kind of vacuum fresh-keeping bag of the utility model, a bag body be from inside to outside successively by PE layers, pet layer, brown paper this three it is laminated be integrated made of；Alternatively, its bag of body be from inside to outside successively by PE layers, pet layer, PE layers, brown paper this four it is laminated be integrated made of；Alternatively, its bag of body be from inside to outside successively by PE layers, pet layer, vmPET layers, PE layers, brown paper this five it is laminated be integrated made of；The utility model outer layer brown paper can play sizing interception；Pet layer can play waterproof, moisture-proof, fresh-keeping, sizing, shaded effect, and the folding triangle at bag bottom both ends prevents freshness protection package from being worn in storage and transportation, storage and conveying box can be replaced to use.The effect that vmPET layer surfaces are aluminized is shading, resisting ultraviolet radiation, has not only extended the shelf-life of content, but also improves the brightness of film, to a certain extent instead of aluminium foil, it may have inexpensive, beautiful and preferable barrier property.

Description

A kind of vacuum fresh-keeping bag

【Technical field】

The utility model is related to food fresh keeping logistics transfer fields, and in particular to a kind of technical field of vacuum fresh-keeping bag.

【Background technology】

Fresh-keeping packaging, storage, transport field is needed to be required for vacuum fresh-keeping bag, traditional vacuum freshness protection package in food, article Sub general outer layer only uses PE layers using kraft paper inner layer, and food or article are placed into interior, pumping machine hot-seal.

But the vacuum fresh-keeping bag of the prior art is when the PE layers of internal layer, it is even to be easy to cause became uneven, therefore It is easy gas leakage during use, causes the food being packaged or article that can not be packed by vacuum insulation；It is traditional simultaneously The compression moulding in the general bottom of vacuum fresh-keeping bag, the both ends that freshness protection package bottom is easily touched in the handling process are easy to wear, Lead to vacuum fresh-keeping bag gas leakage and the fresh-keeping effect that scatters and disappears, so can only be by vacuum freshness retaining bag encasement storage and transportation, therefore it is empty to increase storage and transportation Between and cost.

【Utility model content】

In order to overcome existing prior art deficiency the utility model to provide a kind of vacuum fresh-keeping bag, the device effective solution The both ends that existing vacuum fresh-keeping bag PE layers of uneven easy gas leakage and freshness protection package bottom are easily touched are easy to wear, lead to vacuum freshness retaining Bag gas leakage and the fresh-keeping effect technical problem of scattering and disappearing, the device is simple and effective to be very practical.

The utility model is achieved through the following technical solutions：

A kind of vacuum fresh-keeping bag, a bag body be from inside to outside successively by PE layers, pet layer, brown paper this three laminated be integrated Made of；

Alternatively, its bag of body be from inside to outside successively by PE layers, pet layer, PE layers, brown paper this four laminated be integrated 's；

Alternatively, its bag of body be from inside to outside successively by PE layers, pet layer, vmPET layers, PE layers, brown paper this five it is laminated be one Made of body；

The bottom both ends of the bag body include two folding triangles, the two, which fold triangle, is extended by bag body, is presented For triangle, bagging fold is then carried out by bagging mold and sticks in a bag bottom using glue or adhesive tape.

Preferably, the bagging mold is made of holder and mold block, mold block is fixed on holder, branch Frame fixes the movement during avoiding bagging on the ground, and mold block is that replacement, the mould can be customized according to shape of product It is provided with multiple gas vents above tool block so that during bagging, bag body, which is sleeved in mold block, accelerates exhaust, promotes bagging effect Rate.

The utility model advantageous effect：The utility model outer layer brown paper can play sizing interception；PET (polyethyleneterephthalate) be polyethylene terephthalate, pet layer can play waterproof, it is moisture-proof, protect Fresh, sizing, shaded effect, the folding triangle at bag bottom both ends prevent freshness protection package from being worn in storage and transportation, can make instead of storage and conveying box With.VmPET (polyester aluminizer) layer not only characteristic with plastic film, but also the characteristic with metal.VmPET layer surfaces are aluminized Effect is shading, resisting ultraviolet radiation, has not only extended the shelf-life of content, but also improves the brightness of film, to a certain degree On instead of aluminium foil, it may have inexpensive, beautiful and preferable barrier property.Therefore, utility model device effectively raises The air-tightness of vacuum fresh-keeping bag and fresh-keeping waterproof moisture-proof effect, bag body pressure voltage is higher, can be adapted for the Special foods such as Tea Industry Fresh-keeping packaging, bag bottom edge angle prevent abrasion from leading to gas leakage using triangle is folded, and have very strong practical function.

To make the feature for being further understood that the utility model and technology contents, the utility model attached drawing and embodiment party are referred to Formula, however institute's accompanying drawings it is only for reference with illustrate to use, be not to be limited to the utility model.

【Specific implementation mode】

With reference to Fig. 1-Fig. 6 and embodiment, the utility model is described in further detail.

As shown in Figure 1, the utility model provides a kind of vacuum fresh-keeping bag, bag body 2 is from inside to outside successively by the first PE Layer 103, pet layer 102, brown paper 101 this three it is laminated be integrated made of.

As shown in Fig. 2, the utility model provides a kind of vacuum fresh-keeping bag, bag body 2 is from inside to outside successively by the first PE Layer 103, pet layer 102, the 2nd PE layers 104, brown paper 101 this four it is laminated be integrated made of.

As shown in figure 3, the utility model provides a kind of vacuum fresh-keeping bag, bag body 2 is from inside to outside successively by the first PE Layer 103, pet layer 102, vmPET layers 105, the 2nd PE layers 104, brown paper 101 this five it is laminated be integrated made of.

As shown in Figures 4 and 5：The bottom both ends of the bag body 2 include two folding triangles 4, the two, which fold triangle 4, is Extended by bag body 2, be rendered as triangle, bagging fold is then carried out by bagging mold and sticked in using glue or adhesive tape Bag bottom 3.

The bagging mold is made of holder and mold block, and mold block is fixed on holder, and holder is fixed on ground It is that replacement can be customized according to shape of product that the movement during bagging, mold block are avoided on face, is set above the mold block It is equipped with multiple gas vents so that during bagging, bag body 2, which is sleeved in mold block, accelerates exhaust, promotes bagging efficiency.

However the above-mentioned preferably feasible embodiment of only the utility model, non-therefore limitation the utility model protect model It encloses, according to the made various modifications of above-described embodiment or applies mechanically within this technical solution protection domain.
