Abstract

The disclosure provides a smart heat sealing method for vacuum packaging, comprising steps of: recording a time interval Δt between two adjacent starts of a heating device which is continuously started a number of times; recording a number k of starts of the heating device; obtaining a first heating coefficient p1 based on Δt, obtaining a second heating coefficient p2 based on k, selecting the heating constant t depending on specified parameters and performance of the vacuum package machine, and calculating the heating time T for next operation of the heating device by a formula T=p1*p2*t based on p1, p2, and t. It solves the heat accumulation problem of the heating device caused by too much repeated use or overuse in short time interval, and thus avoids unsuccessful vacuuming and solves the problem of poor heat sealing effect, and greatly improves user experience.

Abstract

The plastic bag for vacuum packing provided by the present invention has embossments which space in longitudinal direction and stagger in transverse direction formed on the inner surface, and thus lots of intercommunicate channels are formed so as to eliminate the possibility to form any air pocket or internal cavity. Meanwhile, air linearly exits from the bottom to the open end, so it takes less time to evacuate the bag. Further, the bag only has one film be embossed, and thus the manufacturing process thereof is simplified and at low cost, and the bag is easy to wash. Moreover, the strength of the bag provided by the present invention is enhanced; especially the anti-avulsion capability is well improved.
