Perhaps, this valve is the sign of its crack that is provided with adhesive-layer, slit or opening.The configuration mode of this adhesive-layer makes it be in one and guarantees to be forced to move and therefore have aud. snl. to take place thereupon when air or water vapour release by valve.
Preferably be positioned at valve on the packing for making a slit on the packaging, lay an adhesive-layer on slit top.
At least the part of adhesive-layer is to be made of the adhesives that is suitable for using simultaneously with food material, because the main purpose of the present invention is exactly to pack for food.
Equally suitably, adhesive-layer is a kind of adhesive tape, and preferably a kind of elastic rubber belt, this adhesive tape itself can adapt to the action of operating packing and can not support from it and throw off.
Similarly, adhesive-layer can be a label, so just can reduce material consumption and can save the required labor content that is used to mark in commission agent.
If be provided with thereon that the packing of valve are made up of non-directional laminated sheet material is useful.In directional material, a slit will produce long and narrow breaking thereon.
Description of drawings
With reference to the accompanying drawings the present invention is described in detail, following accompanying drawing is a purpose and present concrete preferred embodiment of the present invention is illustrated for example.
Fig. 1 is the general view that has according to the packing of valve of the present invention;
Fig. 2 is the process of two different phases that a packing of the with good grounds valve of the present invention in heating tape is shown; Shown in Fig. 2 a is that packing is in cold conditions, and Fig. 2 b is the heated state of packing;
