Description
Technical Field
The utility model relates to a wrapping bag, in particular to high transparent cold-resistant wrapping bag.
Background
The packaging bag is a bag for packaging various articles, so that the goods are convenient to transport and easy to store in the production flow process. Is widely used in daily life and industrial production. Actual figures show that 80% of used plastic bags are finally transported to a garbage piling field area for treatment like ordinary garbage, and only seven percent of the plastic is recycled.
The traditional packaging bag is poor in heat preservation performance, the transparency of some packaging bags with heat preservation functions is low, the requirements of users are difficult to meet, the traditional packaging bag is easy to damage, and the service life is short. Therefore, a high-transparency cold-resistant packaging bag is provided.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a high transparent cold-resistant wrapping bag can effectively solve the problem in the background art.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a high transparent cold-resistant wrapping bag, includes wrapping bag and PVC membrane, the PVC membrane bonds in wrapping bag internal surface, the pressfitting has the polyurethane film between wrapping bag and the PVC membrane, polyurethane film bottom surface bonding has transparent pellosil, the vacuum hole has been seted up with transparent pellosil to the polyurethane film.
Furthermore, a reinforced rubber wire is adhered between the polyurethane film and the packaging bag.
Furthermore, a heat insulation rubber base is bonded at one end of the packaging bag.
Further, the bottom end surface of the transparent silicon film is provided with a PET film.
Compared with the prior art, the utility model discloses following beneficial effect has:
1. this kind of high transparent cold-resistant wrapping bag passes through the adhesive temperature-insulating rubber base of wrapping bag one end, make whole wrapping bag bottom have certain heat preservation function, it makes whole wrapping bag more three-dimensional to separate temperature-insulating rubber base's setting simultaneously, facilitate the use, the reinforcing rubber silk through the adhesion between polyurethane film and the wrapping bag, the toughness of whole wrapping bag has been strengthened, avoid leading to the easy damaged condition of wrapping bag to take place because of external force pulls, through wrapping bag internal surface adhesive's PVC membrane, make whole wrapping bag have good transparency, the polyurethane film through setting up makes the wrapping bag have good mechanical properties, rigidity has simultaneously, hardness and toughness are high, puncture resistance, antifriction, high temperature and low temperature resistance, chemical resistance, oil resistance, gas tightness and fragrance preserving are good, the practicality of wrapping bag has been improved.
2. This kind of high transparent cold-resistant wrapping bag makes the wrapping bag inside have the vacuum and separates the temperature space through the vacuum hole that sets up to effectual transmission that hinders the temperature has further improved the cold-resistant thermal insulation nature of wrapping bag, through the transparent silica gel membrane that sets up, makes the wrapping bag have good corrosion resistance, through the PET membrane that sets up, has improved the high temperature resistance of wrapping bag, avoids the inside storage object high temperature of wrapping bag to lead to the bag body to melt the condition of decomposition and appear.
