Abstract
The utility model relates to a ventilating window for packing materials used for keeping fresh and alive food fresh and prolonging storage period. A ventilating window is arranged on the packing materials. A micro-porous superfine fiber non-woven film is heat sealed or pasted at a ventilating hole, a sealed side or a sealed opening so the utility model has fine air permeability, is waterproof and is capable of preventing bacterial intrusion and spread. The micro-porous superfine fiber non-woven film has a three-dimensional labyrinth structure, high aperture ratio, low cost and air permeability higher than other micro-porous films having planer structure such as core pore membrane, corrosive film, and the like. The ventilating window formed by the micro-porous superfine fiber non-woven film by using hydrophobic high polymer materials can keep the water in the packing materials, prevent the external water from entering and prevent materials from mildewing.
Description
Technical field
The utility model relates to a kind of transom of packing material, is to help prolonging article a kind of manner of packing storage period.
Background technology
In order to prolong the fresh-keeping and storage period of fresh and alive food such as gourd, fruit and vegetable, chicken and duck fishes and shrimps, many packing materials such as packaging bag, packing box and packing chest are all stamped breather hole, what have has also used the silicon window, and this all helps prolonging the storage period of fresh and alive food, but also exists a lot of defectives.The one, breather hole can cause the cross pollution between each packing, promptly has the article in the packing to rot or microbiological contamination, can pass to the interior article of other packings by gas or the liquid that overflows; The 2nd, the article moisture content in the packing is lost greatly, makes outward appearance, mouthfeel, the flavor quality decline of food, or causes the gourd, fruit and vegetable continued growth and ageing, variable color; The 3rd, storage meeting and other article taint of odour or cross pollution in freezer, air-conditioned cold store; Used the packing of silicon window, can make moderate progress to above-mentioned defective, but its permeability to air has been poor, the cost height so seldom use, generally is used for the packing of medicine and medicine equipment on the packing of fresh and alive food.
The utility model content
Technical problem to be solved in the utility model just provides a kind of transom of packing material, overcomes defective and deficiency that existing packing material exists, the requirement of satisfying the fresh-keeping of fresh and alive food and prolonging storage period.
Thinking of the present utility model is that ventilative window is set on packing material, on ventilation mouth (hole) or edge sealing place or sealing part, go up a kind of micropore superfine fibre non-woven film by heat seal or stickup, make it have air permeability and good, but waterproof, and can stop intrusion and the propagation of bacterium.
The utility model is by the following technical solutions:
Be used for the fresh-keeping of fresh and alive food and prolong the transom of the packing material of storage period, it is characterized in that: the transom of described packing material is to stick the non-fiber fabric film on the ventilation mouth of packing material or edge sealing place or sealing part.
In order to make transom have air permeability and good, waterproof again, and have the intrusion that can stop bacterium and the function of propagation.The aperture of the micropore superfine fibre non-woven film of the transom of described packing material is 0.01～10 μ m.
The aperture of the micropore superfine fibre non-woven film of the transom of described packing material is 0.05～3 μ m.
The fibre fineness of the micropore superfine fibre non-woven film of the transom of described packing material is 0.001～0.8den.
For the loss of moist that prevents products to be packaged and the invasion of external moisture, the micropore superfine fibre non-woven film of the transom of described packing material has hydrophobic nature.
The shape of the transom of described packing material can be that circle or ellipse can also be square or rectangle or bar shaped.
In order to guarantee air permeable effect and to be convenient to gas flow in the packing material, exchange, the transom of described packing material should be arranged on packing material the side and above.
The transom of described packing material can be provided with 1～12.
Consider the intensity and the permeability to air of the transom that micropore superfine fibre non-woven film is made, the area of described each transom of packing material is 0.8～50cm
2, its minimum diameter is not less than 1cm.
Can utilize micropore superfine fibre non-woven film to have certain volume, immersion has medicine fresh-keeping or anticorrosion or insect protected or sterilizing function on the transom of described packing material.
Beneficial effect
Fresh and alive food such as gourd, fruit and vegetable needs to breathe and will give off gases such as ethene, ammonia, carbon dioxide in storage, be stored in the air-conditioned cold store some need with air inerchange in the storehouse, micropore superfine fibre non-woven film is a kind of maze-type structure of three-dimensional, the percent opening height, its permeability to air is far above the microporous barrier of other planar structure, as nucleopore membranes, corrosive film etc., and with low cost.The transom that the High molecular material of employing hydrophobic nature is made micropore superfine fibre non-woven film can make the moisture in the packing material not lose, and can also prevent the invasion of outside moisture, has the ability of not going mouldy again.
The transom made from micropore superfine fibre non-woven film, heat seal or stick on the various packing materials such as preservative film, freshness protection package, packing box or packing chest easily, the packing material that promptly is suitable for thermoplastic material, be fit to the paper packaging thing again, the packing material that can also be used for composite material, can making originally, common packing material has had fresh-keeping function.
Can utilize the characteristics that have higher volume in the micropore superfine fibre non-woven film of transom, on transom, immerse antistaling agent, anticorrosion, insect protected or disinfecting drug, more help the fresh-keeping of fresh and alive food and store.
The aperture of the micropore superfine fibre non-woven film of the transom of packing material is 0.01～10 μ m, but actv. stops bacterium and bacterial mass invasion and propagation, avoids the cross pollution of article in each packing.
The transom of this packing material also helps the degraded of agricultural chemicals.To food, the article that need after packing, sterilize, be of value to sterilizing gas and enter and discharge.
The transom of this packing material is not only applicable to food, can also be used for the packing of medicine equipment.
The utility model is described in further detail below in conjunction with drawings and Examples:
