[China Packaging Network News] With the continuous development of materials science and people's awareness of food packaging safety, environmental safety and other aspects of continuous improvement and attention, from the material to the appearance of the kink packaging has also been continuously developed and improved, but how to make it more Good application and play its biggest role, we also need to go deeper to explore the study.
With the continuous development of materials science and people’s increasing awareness of food packaging safety and environmental safety, kink packaging has also been continuously developed and improved from materials to form factors. However, how to apply it better and exert it? The greatest role requires us to study the research in more depth.
Kink wrappers are mainly used for the packaging of confectionery, chocolate, preserved fruit, beef jerky and other foods. This type of packaging started in the early 19th century in London, England, when the candy store in London used paper-packed sweets, which were later used by confectioners. A wrapping paper with a trimmed edge or lace wraps the candy in a kink. Kinked packaging still retains its elegance and ease of use. At the same time it protects the candy from moisture, oxygen and various other contaminants.
The first material used for kink packaging was paper. Later, transparent cellophane glass appeared instead of paper kink packaging. Later, various plastic substrate twist films were developed, such as polyethylene (HDPE) twist film, Polyvinyl chloride (PVC) twisted film, cast polypropylene (CPP) twisted film, polyester (PET) twisted film. Celluloid cellophane has been widely used in kink packs for a long time since its development in the 1920s. Due to its excellent kink properties and excellent transparency, it has poor moisture resistance, flammability, and serious pollution. The appearance of rigid polyvinyl chloride (PVC) twisted conjunctiva in the 1980s was greatly affected and was basically replaced by a rigid polyvinyl chloride (PVC) twisted conjunctiva. The rigid polyvinyl chloride (PVC) twisted film has excellent kink properties, transparency, moisture resistance, and balanced vertical and horizontal properties, and was widely used in the early stage. As polyvinyl chloride (PVC) contains some toxic additives and plasticizers, it may seep or gasify; some additives may interfere with human endocrine and some may increase the risk of cancer; incineration of polyvinyl chloride (PVC) waste can cause cancer. As a result of evil and pollution of the atmosphere, polyvinyl chloride (PVC) kinked films have been kinked by polyester (PET) films in Europe, the United States, Japan, Korea, and Taiwan. In Asia, Africa, South America and other regions, the impact of polyvinyl chloride (PVC) films on the environment has been neglected, and polyvinyl chloride (PVC) films are still used for kink packaging.
