Description

Packaging bag designed by 3R concept Technical Field The utility model relates to the field of packaging bags, in particular to a packaging bag designed by a 3R concept. Background In the packaging field of various products, the requirements for moisture resistance and humidity resistance are very common. Especially, products sensitive to humidity such as food, medicines and electronic products are extremely easy to deteriorate and damage once wetted, and the quality and the service life of the products are seriously affected. When the conventional packaging bag is used for solving the damp-proof problem, the conventional packaging bag has the defects that a part of the packaging bag is internally provided with a dry moisture absorbent, but when the moisture absorbent reaches a saturated state, moisture can be reversely released, so that the product is increased in damp risk. Secondly, the dry moisture absorbent is usually placed in the same space, and the moisture absorption capacity cannot be flexibly distributed according to different requirements of different parts of the product on humidity, for example, in some irregularly shaped product packages, certain corner areas are difficult to obtain sufficient moisture absorption protection. Thirdly, when the dry moisture absorbent fails, the dry moisture absorbent is difficult to replace independently, and the dry moisture absorbent is often required to be discarded together with the whole packaging bag, so that resource waste and cost rise are caused. Fourth, when the wrapping bag is used, destroyed the wrapping bag when opening, unable continuous re-use, then discarded, cause very big waste. Disclosure of utility model The utility model aims to provide a packaging bag designed by a 3R concept, so that the problems that a dry moisture absorbent in the existing packaging bag is easy to get damp when being contacted with a product, the moisture absorption and the distribution are uneven, and the moisture absorbent is difficult to replace independently are solved. In order to solve the problems, the utility model adopts the following technical scheme: The packaging bag comprises a first film material, a second film material and a non-woven fabric material, wherein the non-woven fabric material and the first film material are bonded through seal ironing, a plurality of independent dry moisture absorbent packaging cavities are formed between the middle part of the inner side of the bag body and the bag bottom, the dry moisture absorbent packaging cavities are sealed on one side close to the bag bottom through a first clamp chain so as to facilitate replacement of dry moisture absorbent, the second film material and the first film material of the sealed and ironed non-woven fabric material are bonded to form a product containing cavity, a bag opening is formed at one end opposite to the bag bottom in a non-seal ironing mode, and the bag opening is sealed through a second clamp chain so as to facilitate opening and sealing of the product containing cavity. Preferably, the direction from the bag mouth to the bag bottom is taken as the length direction, a plurality of independent dry moisture absorbent packaging cavities extend along the length direction, and each adjacent dry moisture absorbent packaging cavity is separated by a sealing and ironing connecting line. Preferably, the first film material, the second film material and the non-woven fabric material are made of a single material, so that the recycling of the packaging bag is facilitated. Preferably, the first film material and the second film material are high-density polyethylene film materials, and the non-woven fabric material is polyolefin non-woven fabric material prepared by flash evaporation technology. Preferably, the thickness of the first film material and the second film material is 60-100 μm. Preferably, the nonwoven material is 75g/M 2 of H1075B breathable material or 70g/M 2 of M7001 breathable material. Preferably, the number of the dry moisture absorbent packaging cavities is 3-10. Preferably, the tooth distance of the first clamp chain and the second clamp chain is 1.2mm, and the tensile strength is more than or equal to 15Mpa. Preferably, the barb angles of the first clip chain and the second clip chain are 30 degrees, and the engagement depth is 0.5mm. Preferably, the first clamping chain for sealing the dry moisture absorbent packaging cavity can be one or a plurality of clamping chains, so that the replacement of the dry moisture absorbent is realized more conveniently. According to the present utility model, there is provided a package comprising a package body comprising a product accommodating chamber and a plurality of independent dry moisture absorbent packaging chambers.
