Description
Technical Field
[0001] The utility model relates to the field of packaging materials, in particular to a frozen product packaging box. Background Art
[0002] At present, more and more pre-prepared dishes (non-cooking packages) that need to be refrigerated (or frozen) are packaged in vacuum bags and sealed. After vacuum sealing, the vacuum bags are placed in corrugated paper boxes and then stored in a refrigerator (or freezer). Since the current corrugated paper boxes are made of corrugated paper cut, folded and assembled as shown in the patent announcement document JPH0744512U, there is a problem with the packaging box made of corrugated paper of this structure, that is, there is no waterproof coating on the surface of the corrugated paper of this structure, and there is a probability of water accumulation or condensation in the refrigerator (non-freezer), so the packaging box made of corrugated paper of this structure must be coated with a layer of plastic film on the surface (the plastic film is not bonded to the packaging box) for waterproofing, but if the coated plastic film is damaged during stacking by workers, the entire plastic film will lose its waterproofing effect. Utility Model Content
[0003] Aiming at the above problems, the utility model provides a frozen food packaging box.
[0004] The technical solution adopted by the utility model is as follows:
