In view of the above-mentioned defect or not enough among the prior art, this application aims at providing a low temperature resistant plastic packaging bag for food freezing, including the sack that the wrapping bag set up at the wrapping bag top, the below that the wrapping bag is located the sack is provided with first sealing strip and second sealing strip respectively, one side of wrapping bag is provided with the gas vent, the inside intercommunication of gas vent has exhaust mechanism, exhaust mechanism's internally mounted has sealing mechanism, the outside coating of wrapping bag has the hydrophobic layer, the gas vent sets up and is located between first sealing strip and the second sealing strip, exhaust mechanism is including setting up the blast pipe in the gas vent inside, one side of blast pipe is provided with the air duct, the top of air duct is provided with the exhaust tube with manual pump looks adaptation, sealing mechanism includes that the screw thread cup joints the sealed lid in the air duct one end outside, the inboard of sealed lid is provided with the ejector pin that is located the air duct inboard, the outside cover at the ejector pin middle part cup joints the sealing washer in the air duct inside, and one side that the ejector pin kept away from is provided with sealed ball.
The beneficial effects are that:
1. this a low temperature resistant plastic packaging bag for food is frozen can carry out dual seal through setting up first sealing strip and second sealing strip on the wrapping bag to the position of sack, simultaneously through setting up the gas vent between first sealing strip and second sealing strip for the wrapping bag is when bleeding through manual pump, can open first sealing strip pressfitting, second sealing strip, and when the wrapping bag is accomplished and is bleeding again with the second sealing strip pressfitting, in order to guarantee that manual pump can seal the wrapping bag before dismantling the second sealing strip, improves sealing performance of sealing strip to the sack.
2. This a low temperature resistant plastic packaging bag for food is frozen uses through sealed lid, ejector pin, sealing washer and sealing ball's cooperation for the wrapping bag is behind carrying out the extraction opening through the manual pump, and accessible sealing ball seals the blast pipe after the second sealing strip pressfitting before not dismantling the manual pump, in order to avoid at the in-process that the manual pump was dismantled, outside air can be through the gas vent to the inside air that gets into of wrapping bag, and then guarantees that the inside air content of wrapping bag is lower, thereby avoids too much and the air contact of food, makes the food be difficult for producing deterioration.
