Description
Technical field
The utility model belongs to the storing technology field, relates to a kind of packaging bag, particularly a kind of air-regulation type packaging bag.
Background technology
Conventional aluminized plastic film bag color is very beautiful, and visual impact is strong, simultaneously certain lucifuge barrier is arranged again, is generally used on packaging for foodstuff and the daily necessities packing.Because the opacity of aluminizing and causing, the customer can not directly see the fresh-keeping degree of content when buying commodity.At present, the fruits and vegetables flexible packaging mainly contains following three kinds of modes: 1, vacuum freezing flexible packaging: fruits and vegetables are packed in the common PE bag, the freezing preservation of vacuum seal, this packing need vacuumize in process of manufacture, complicated operation, cost height, and this packing can not continue to keep the respiratory Minimum requirements amount of fruits and vegetables " life live body ", fruits and vegetables substrate of respiration when causing " anaerobic respiration " anaerobic respiration can not be by exhaustive oxidation, the result forms actually and material such as acetaldehyde, easily causes the spoiled, rotten of fruits and vegetables and decays; 2, micro-wave oven heating automatic deflation flexible packaging: fruits and vegetables are put into the PE composite film packaging bag that has ventilative line, sealing, chilled storage, sack expansion automatic deflation during heating and can explosion, but this packaging bag only is fit to need the fruits and vegetables of consumption fast, and resistance tocrocking is relatively poor; 3, fruit and vegetable air-conditioning flexible packaging: generally adopt the PE composite package film, under 0～4 ℃ of temperature conditions, by the adjusting of packing factors such as interior ambient temperature, humidity, gas concentration is controlled to suppress the respiration of fruits and vegetables and reduced its water evaporates quantity, and then prolong the used life of fruits and vegetables.But this packaging bag to the requirement of complex film than higher, how to select membraneous material, becoming the most important research direction of air-regulation type packaging bag, is content very important in the Package Testing to test ventilative or saturating performance such as wet, and the quality of barrier property determines the shelf-life of product design.Therefore, a kind of membraneous material with high obstructing performance of exploitation is with a wide range of applications.
Summary of the invention
The purpose of this utility model is to have the problems referred to above at existing technology, has proposed a kind of air-regulation type packaging bag, and its simple in structure, good barrier property can prolong the fruits and vegetables shelf life effectively, and can observe packaging bag inside intuitively.
The purpose of this utility model can realize by following technical proposal: a kind of air-regulation type packaging bag, comprise the preceding front cover and the back front cover that are joined together to form sealed chamber, it is characterized in that, front cover comprises PE layer one, aluminium coated, pet layer and CPP layer from outside to inside before described, and described back front cover comprises PE layer two, ink lay and co-extrusion PVDC layer from outside to inside.
In the technical program, the PET formal name used at school of employing is polyethylene terephthalate, and the PVDC formal name used at school is polyvinylidene chloride, and the PE formal name used at school is polyethylene, and the CPP formal name used at school is cast polypropylene.This packaging bag adopt be coated with aluminium coated pet layer as packaging bag before front cover, aluminium coated namely can improve the barrier of PET material, can print again, and is simple in structure, cost is lower; It also adopts PE layer and co-extrusion PVDC layer as the back cover material, makes the back front cover to have an X-rayed, and is easy to the freshness that the customer observes product in the packaging bag, and PVDC shapes easily, and degradable again prevents white pollution, energy-conserving and environment-protective simultaneously.
In above-mentioned air-regulation type packaging bag, the thickness proportion of described aluminium coated and pet layer is 1:5.
In above-mentioned air-regulation type packaging bag, the thickness proportion of described pet layer and CPP layer is 1:4.
In above-mentioned air-regulation type packaging bag, described pet layer and CPP layer are bonded together by ultraviolet cured adhesive or polyurethane glue.
In above-mentioned air-regulation type packaging bag, described co-extrusion PVDC layer is that 2～8 layers of individual layer PVDC film co-extrusion are into a single integrated structure.
In above-mentioned air-regulation type packaging bag, described ink lay is pure dissolubility or water-soluble environment protective printing ink.
In above-mentioned air-regulation type packaging bag, be bonded together by ultraviolet cured adhesive or polyurethane glue between described PE layer two and the ink lay.
In above-mentioned air-regulation type packaging bag, be bonded together by ultraviolet cured adhesive or polyurethane glue respectively between described ink lay and the co-extrusion PVDC layer.
In above-mentioned air-regulation type packaging bag, be filled with CO in the described chamber
