Abstract
The invention belongs to the technical field of packaging bags and particularly relates to a packaging bag of a double-layer structure. An inner bag with the structural shape corresponding to that of an outer bag is embedded in an inner cavity of the outer bag of a bag-shaped structure. The left side edge and the right side edge of the outer bag are each provided with a sealing edge strip integrated with the outer bag. An air inflow/outflow pipe is arranged at one end of the upper edge of the outer bag and provided with two pipe ports. One pipe port is communicated with an inner cavity of the inner bag. The other pipe port is communicated with the inner cavity of the outer bag. A sealing glue strip is arranged on the side edge of the upper top of the air inflow/outflow pipe and can seal the two pipe ports of the air inflow/outflow pipe respectively. All the parts are matched to form the packaging bag of the double-layer structure. The inner bag is used for performing vacuum packaging on articles, the outer bag is used for performing inflation to protect the articles, and therefore the articles can be effectively prevented from being pressed, broken and deformed. The packaging size and the weight of the articles are reduced, packaging and transporting cost is reduced, and a dispute between a buyer and a seller is avoided. The packaging bag is simple in body structure, capable of being cyclically used, capable of saving energy, environment-friendly, simple and fast in packaging and environmental to the using environment.
Description
Technical field:
The invention belongs to packaging bag manufacturing technology field, be specifically related to a kind of double-deck packaging bag, there is vacuum packaging and safeguard function, to substitute existing breakables and fruit packaging bag.
Background technology:
In modern society, packaging bag has become the most common items for packing various articles for use, and it can make goods convenient transport in production circulation process, easily stores, is widely used in daily life and commercial production; Real figure shows, and has the packaging bag after 80% use in existing packaging bag, final equally with conventional rubbish is transported to landfill process, only has the packaging bag of 7% to be recovered and recycles; Packaging bag is divided into plastic packaging bag and combined package bag by manufacture craft, and plastic packaging bag comprises Polywoven Bag and plastic film bag, Polywoven Bag have lightweight, intensity is high and resistant to corrosion feature, after adding plastic sheeting liner, can be moistureproof damp proof.Vacuum bag also claims decompression packaging, is all extract the air in packing container out sealing, and maintain in bag and be in height decompression state, air starvation is equivalent to hypoxemia effect, makes germ not have life condition; The Main Function of vacuumizing-inflating packing is guaranteed the quality except function except the deoxygenation that vacuum packaging possesses, and also has resistance to compression, choke and fresh-keeping, can more effectively make food keep original color, shape and nutritive value for a long time.At present, due to the high speed development of internet and the rapid emergence of electric business, a large amount of net purchase commodity need to be transported by logistics or express delivery, because object is too many, add that conveying people quality is uneven, barbarous sorting and transport are unavoidably, cause frangible yielding and treasure to be damaged, even if claim damages successfully, limited reparation at all can not offset object damage loss, property and waste of time is caused to both parties, the manner of packing of traditional thickening packaging or filled with foaming material etc., add the weight and volume of transport object, correspondingly add traffic cost, and use is all disposable material, irreversible pollution is caused to environment.Therefore, research and develop a kind of double-deck packaging bag, there is vacuum packaging and safeguard function, can recycle, reduce environmental pollution, for packing and transporting frangible yielding and treasure, have very much social value and application prospect.
Summary of the invention:
The object of the invention is to the shortcoming overcoming prior art existence, seek to design a kind of double-deck packaging bag, there is vacuum packaging and safeguard function, can recycle, reduce environmental pollution, for packing and transporting frangible yielding and treasure.
To achieve these goals, agent structure of the present invention comprises outer bag, inner bag, sealing edge strip, turnover tracheae and sealing joint strip, the inner bag with outer bag counter structure shape is nested with in the inner chamber of the outer bag of bag shaped structure, the cavity of inner bag is less than the inner chamber of outer bag, the upper side sealing of outer bag and inner bag is pasted for flush configuration, the limit, the left and right sides of outer bag is equipped with the sealing edge strip with outer bag integral structure, the cavity volume of the sealing width of edge strip and outer bag is in direct ratio, upper edge one end of outer bag is provided with turnover tracheae, turnover tracheae is provided with two mouths of pipe, one communicates with the inner chamber of inner bag, another communicates with the inner chamber of outer bag, the upper top side of turnover tracheae is provided with sealing joint strip, two ferrules of turnover tracheae are lived by sealing joint strip respectively, each part fits forms double-deck packaging bag, inner bag is PE, NY/AL/RCPP and NY/PE for material during sheathing foodstuff.
When the present invention uses, inner bag is put into by needing the article of packaging, air pump, inflator or the artificial turnover tracheae that passes through is used to be blown into air in outer bag inner chamber, air in outer bag constantly extrudes inner bag and is extruded by the air in its inner chamber to make inner bag form vacuum state, after outer bag expands, inflation terminates, and closes turnover tracheae, complete the packaging of article with sealing joint strip; When taking out the article in inner bag, first the sealing joint strip on turnover tracheae is torn, release the gas in outer bag inner chamber, making enter gas in inner bag inner chamber and fill out, then pulling items simultaneously, folding double-deck packaging bag for recycling.
The present invention compared with prior art, adopts double-decker, and inner bag is used for vacuum packing goods, outer bag is used for inflating protection article, effectively prevents article pressurized breaking deformation, reduces article packaging volume and weight, reduce packaging and traffic cost, avoid both parties' dispute; Its agent structure is simple, can recycle, energy-conserving and environment-protective, pack fast easy, and environment for use is friendly.
Accompanying drawing illustrates:
Fig. 1 is agent structure principle schematic of the present invention.
Fig. 2 is the effect schematic diagram after connection with wrapping of piece of the present invention.
Detailed description of the invention:
Also by reference to the accompanying drawings the present invention is described further below by embodiment.
