Abstract

It the utility model is related to flexible packing material technical field, more particularly to a kind of new thermophilic digestion aluminum foil sack easily torn, including bag body and it is opened in bag tearing port at body edge, laser wires are penetrated with laser device along the tear direction of the tearing port on the bag body, the laser wires are linearly.The new thermophilic digestion aluminum foil sack that easily tears of this reality, when tearing sack along the tear direction of tearing port, effect that packaging bag can reach two-sided straight line, easily tear, and boiling is not stratified.

Description

A kind of new thermophilic digestion aluminum foil sack easily torn

Technical field

It the utility model is related to flexible packing material technical field, and in particular to a kind of new thermophilic digestion Aluminium Foil Package easily torn Pack.

Background technology

As shown in Figure 1, common thermophilic digestion packaging bag 1 of the prior art, is generally equipped with the edge sealing of bag body transverse direction Tearing port, when tearing port is torn by external force, stress distribution is uneven, and not only hardly possible, which tears and easily deviates straight line, causes in packaging bag Food splashes, and arrow represents tear direction in Fig. 1.High-temperature retort bag will more make it have line easy-tear performance, of the prior art general Logical thermophilic digestion packaging bag 1 mainly makes packaging bag possess line easy-tear performance using the characteristic of easily tearing of material in itself, but tear direction without Method controls.

Utility model content

The purpose of this utility model is that being directed to deficiency of the prior art, and provide a kind of new thermophilic digestion easily torn Aluminum foil sack, when tearing, the effect of can reach two-sided straight line, easily tearing.

To achieve the above object, the technical solution that the utility model is taken is：A kind of new thermophilic digestion aluminium foil easily torn Packaging bag, including bag body and be opened in bag tearing port at body edge, along the tear direction of the tearing port with swashing on the bag body Light laser apparatus has penetrated laser wires, and the laser wires are linearly.

Wherein, the bag body ecto-entad includes outer membrane, intermediate layer film and internal layer membrane successively, outer membrane, Intermediate layer film and internal layer membrane pass sequentially through adhesive and are combined.

Wherein, the laser wires puncture the outer membrane for laser device and are formed.

Wherein, the laser wires only puncture the outer membrane for laser device and are formed.

Wherein, the laser wires are dotted line, and the several points for forming the dotted line are described outer by the breakdown of laser device Layer film and formed.

Wherein, the outer membrane is pet film.

Wherein, the intermediate layer film is aluminium foil film, or the intermediate layer is nylon film and aluminium foil film.

Wherein, the internal layer membrane is polypropylene film.

Wherein, the adhesive is polyurethane.

The beneficial effects of the utility model：

A kind of new thermophilic digestion aluminum foil sack easily torn of the utility model, in process of production, cutting process dress There is dress laser device, using the photon of the high load capacity energy of the strong beam of laser device, bag body surface face carries out physics Gasification reaction, (ultraviolet) photon of high load capacity energy interrupt plastic material, the chemical bond in surrounding medium, material occur non-thermal Process is destroyed, and by controlling laser power, it is just punctured a bag surface layer pet film, is hit Wear position and lacked this layer of rigid material of pet film, packaging bag presents and easily tears effect, and tearing port is set Laser breakdown linear edge, when tearing sack along the tear direction of tearing port, packaging bag can reach two-sided straight line, The effect easily torn.

Brief description of the drawings

Fig. 1 is the tearing effects figure of common thermophilic digestion packaging bag.

Fig. 2 is the structure diagram of the new new thermophilic digestion packaging bag easily torn of this reality.

Fig. 3 is the tearing effects figure of the new new thermophilic digestion packaging bag easily torn of this reality.

Reference numeral：

The common thermophilic digestion packaging bags of 1-, this reality of the 2- new new thermophilic digestion packaging bag easily torn, 3- laser wires.

Embodiment

The utility model is further described with the following Examples.

Fig. 1 is the structure diagram of existing plastic packaging bag, since background technology had been described in detail, herein no longer to Fig. 1 Repeat.

As shown in Fig. 2, the new new thermophilic digestion aluminum foil sack 2 easily torn of this reality, including bag body（Figure is mark）With open up Tearing port at bag body edge（It is not shown）, penetrated along the tear direction of the tearing port with laser device on the bag body Laser wires 3, and laser wires 3 are linearly, so that bag body, when tearing, bag body is two-sided to be torn along laser wires 3, i.e., along straight Line is torn, and is easily torn, just as shown in figure 3, arrow represents tear direction in Fig. 3.

Finally it should be noted that above example is only illustrating the technical solution of the utility model, rather than to this reality With the limitation of novel protected scope, although being explained with reference to preferred embodiment to the utility model, this area it is general Lead to it will be appreciated by the skilled person that can be to the technical solution of the utility model technical scheme is modified or replaced equivalently, without departing from this The spirit and scope of utility model technical solution.
