Specific embodiment
As shown in Figures 1 to 5, with the valve bag of composite construction, comprising: bag wall portion, closure and sack portion；Wherein,
Space in bag is constituted between bag wall portion；Closure is formed in the periphery in bag wall portion and by space-closed in bag, and sack portion is set to
The edge in bag wall portion and the sack for forming space in a connection bag；Wherein, bag wall portion includes: pet layer, metal aluminium coated, and
One PE layers, bubble layer and the 2nd PE layers；Pet layer is set to the outside of metal aluminium coated and is located at the outermost in bag wall portion；First
PE layers between the gentle alveolar layer of metal aluminium coated；The 2nd PE layers of inside positioned at bubble layer and the most inner side positioned at bag wall portion.
So, metal aluminium coated can play the effect for preventing electrostatic, and bubble layer can play the work for preventing impact
With, and the 2nd PE layers can improve sound construction degree.
Specifically, closure includes: pet layer, metal aluminium coated, the first PE layers, bubble layer and the 2nd PE layers；Wherein,
2nd PE layers of setting are between two layers of bubble layer, two the first PE layers of outsides positioned at two bubble layers；Two metal aluminium coateds
Positioned at two the first PE layers of outsides；Two pet layers are separately positioned on the outside of two metal aluminium coateds.Here the 2nd PE layers
The intensity of the combination at closing can especially be improved.
Specifically, sack portion includes: pet layer, metal aluminium coated, the first PE layers, bubble layer, the 2nd PE layers and release paper
Layer；Wherein, pet layer is set to the outside of metal aluminium coated and is located at the outermost in sack portion；First PE layers be located at bubble layer and
Between metal aluminium coated；The 2nd PE layers of inside positioned at bubble layer；Off-style paper layer is located at the 2nd PE layers of inside.Sack portion is additional
Release paper or release film as off-style paper layer and then realize self-styled function.As a kind of scheme, off-style paper layer and the 2nd PE layers
Between be equipped with melt layer.
Specifically, metal aluminium coated is the coating containing aluminium.In other words, metal aluminium coated is aluminium coated.Aluminium coated is compared
Other metal aluminium coated light weights and easy to process.
Bubble layer is at least made of PET material.
Specifically, the value range of the ratio of the width W2 of the width W1 and closure of sack is 5-150.Such benefit
It is the Assurance of Size structural strength by suitable closure, if the width of closure may be less likely to will appear bad sealing
The case where, if but closure is excessive and will cause the waste of material.The width of sack determines the capacity of sack, so bag
The width of mouth is also required to carry out matched design.Similarly, the ratio of the catercorner length D1 of the width W2 and bag wall portion of closure
Value range be 10-200.
In order to guarantee self-styled firm degree, the value range of the ratio of the height H3 of the height H2 and bag wall portion of sack
For 10-100.
The basic principles and main features and advantage of the utility model have been shown and described above.The technical staff of the industry
It should be appreciated that above-described embodiment does not limit the utility model in any form, it is all by the way of equivalent substitution or equivalent transformation
Technical solution obtained, all falls in the protection scope of the utility model.
