Description

Technical Field

[0001] The utility model relates to the technical field of plastic soft packaging, in particular to a plastic soft packaging with strong sealing performance. Background Art

[0002] Flexible packaging refers to packaging whose container shape can change after filling or taking out the contents. Various bags, boxes, sleeves, packages, etc. made of paper, aluminum foil, fiber, plastic film and their composites are all flexible packaging. With the advancement of technology and the development of the market, customers' requirements for product quality and service are constantly improving, and competition among enterprises is becoming increasingly fierce. The flexible packaging industry in the modern sense of the country has a development history of more than 20 years. Over the past 20 years, the domestic flexible packaging industry has grown rapidly from small to large, showing an obvious trend of groupization and scale. There are two major types of flexible packaging, namely stretch wrap packaging and various bag packages. Stretch wrap packaging consists of plastic film that has not yet formed a packaging shape. It is to simply wrap the film around one or more products to be packaged and fix it in place in some form. Plastic bags are made into a certain shape before or while the products are being put in. The most common method is to heat seal the plastic edges to form this shape.

[0003] As disclosed in CN108001834A, a plastic packaging box with strong sealing performance is disclosed, wherein the first oblique extension part and the second oblique extension part completely enter the card slot, and the lower end of the second oblique extension part can be elastically opened and contacted with the third vertical extension part. When the upper ends of the first oblique extension part and the second oblique extension part abut against the arc-shaped lower surface of the second horizontal extension part, as the first vertical extension part continues to enter the card slot, the first vertical extension part supports the first oblique extension part upward, and the first oblique extension part supports the second oblique extension part, and the arc-shaped lower surface of the second horizontal extension part The first oblique extension portion and the second oblique extension portion will have a downward reverse supporting force, and the upper end of the first oblique extension portion drives the upper end of the second oblique extension portion to slide along the arc-shaped lower surface of the second horizontal extension portion toward the third vertical extension portion, and the lower end of the second oblique extension portion gradually slides into the accommodating groove along the inner side surface of the third vertical extension portion and is stuck in the blocking portion, automatically realizing double sealing. However, it is inconvenient to store and carry during use, and its sealing is poor. For this reason, we propose a plastic soft package with strong sealing performance to solve the problem that traditional packaging is inconvenient to store and carry and has poor sealing performance.
