Adhesive tape for sealing boxes and manufacturing method thereof

Abstract

The invention provides an adhesive tape for sealing boxes. The adhesive tape is obtained by adopting a cold drink product packaging film as a substrate and coating a pressure-sensitive adhesive. The cold drink product packaging film is a composite thin film; and the inner surface of the cold drink product packaging film is a heat-sealing layer, while an outer surface is a biaxially tensioned polypropylene thin film layer and is printed with patterns and characters. The embodiment of the invention utilizes the waste composite packaging film in cold drink production, thereby effectively solvingthe problems of waste and overstocked products brought by the waste packaging film; the property of the obtained adhesive tape completely meets the application requirement; and the adhesive tape has quite significant economic benefit.

Description

technical field [0001] The invention provides an adhesive tape for sealing a box and a manufacturing method of the adhesive tape, which belong to the field of packaging product processing. Background technique [0002] Adhesive tapes are used in a large amount in the packaging and sealing of transportation and storage items in various enterprises. According to the requirements and characteristics of products in the storage and transportation process, corresponding adhesive tapes need to be selected. For example, the adhesive tape commonly used in the packaging of cold drink products is made of biaxially oriented polypropylene film (BOPP) as the base material coated with pressure-sensitive adhesive, which requires the adhesive tape for sealing to be in normal temperature or freezing conditions. Both can maintain good tensile strength, heat seal strength and flexibility. [0003] In order to highlight the product image of the company and enhance the reputation of the company,...

Problems solved by technology

[0004] On the other hand, due to product upgrading, production-oriented enterprises will have a large amount of unused packaging film being discarded and become a backlog of inventory. For example, the types and varieties of cold drink products on the market are increasing year by year. In order to meet production needs, a large number of packaging films are correspondingly required , and the market life cycle of most cold drink products is very short. Once the production is stopped, the packaging film will be discarded. If it is not handled in time, it will increase the pressure on the warehouse and lead to an increase in production costs.

These product packaging films are all kinds of composite films processed according to product characteristics, and they are directly scrapped, which not only causes capital losses (only based on the applicant's own incomplete statistics, only the cold drink production department's annual loss of such funds reaches 300- RMB 5 million), which also increases the burden of environmental protection
