Description

Technical Field

[0001] The utility model relates to the technical field of packaging bags, in particular to a vacuum compression bag with adjustable spatial distribution. Background Art

[0002] The origins of vacuum packaging technology can be traced back to early human explorations into food preservation. Initially, simple vacuuming tools and sealing methods were used to extend the shelf life of food. With the advancement of the Industrial Revolution and the development of materials science, vacuum packaging bags gradually evolved from crude, simple packaging to today's versatile packaging featuring advanced materials. The widespread use of plastics in the mid-20th century provided a significant opportunity for the development of vacuum packaging bags. Plastic film, with its advantages of flexibility, sealing, and low cost, quickly became the primary material for vacuum packaging. Compared to traditional plastic bags, vacuum packaging bags offer advantages such as freshness preservation, moisture and mildew resistance, pressure and shock absorption, and reduced bulk.

[0003] Currently, existing sealed bags have only one inner cavity without any partitioning function. When storing multiple items that need to be used at the same time, multiple sealed bags are often required. This makes the sealing, taking out, and resealing processes quite cumbersome, time-consuming, and inconvenient to manage. Therefore, a vacuum compression bag with adjustable space distribution is needed. Utility Model Content
