For consumers, the transparency of product information and the transparency of packaging are very popular. Because of this, the global transparent barrier packaging film market has witnessed steady growth in the food industry in the past few years, and this trend is expected to continue.
In the food industry, this packaging film can provide moisture-proof and waterproof gas packaging for food, and its high barrier properties can extend the shelf life of food. Processed products, such as fruits, vegetables and dairy products, are the main categories of packaging using transparent barrier films. By using this kind of packaging, food manufacturers can better show customers the freshness of their products as a means of increasing sales.
Transparent barrier packaging film is a packaging film composed of different types of polymers based on different applications. The global food industry is the biggest factor driving the demand for this film market, occupying a market share of 57.4%.
Transparent barrier packaging film used in the food industry
From the perspective of the end user, the increase in the consumption of processed video and ready-to-eat food is a major stimulus.
Three emerging trends that are currently driving the global transparent barrier packaging film market are:
• Innovation of transparent barrier film
• Recycling of transparent barrier films
• The growing market of biodegradable films
Trend 1: Innovation of transparent barrier films
In the transparent film market, product innovations have also appeared, such as the elimination of chlorine content. The transparent film contains chlorine, which will increase carbon emissions and energy consumption during the manufacturing process. After being discarded, non-degradable waste will be generated. Some suppliers have introduced innovative products that can solve all the problems mentioned above.
Trend 2: Recycling of transparent barrier films
Many waste disposal agencies have taken advantage of these opportunities and introduced innovative recycling technologies to complete the recycling of aluminum foil films and chlorine-containing plastic films. "
A waste disposal agency in the UK has developed a pyrolysis process that can burn transparent films in the combustion chamber; the carbon in the residue is composed of 79% liquid carbon and 21% gaseous carbon. In this process, no carbon dioxide is produced.
Because the room does not contain oxygen, the liquid carbon and gaseous carbon produced in this process can be transported to different places to meet fuel and energy needs.
Trend 3: The growing market of biodegradable films
Polyhydroxybutyrate (PHBV) is one of the earliest developed biodegradable packaging film materials; it is a polyester produced with bacteria and has properties similar to PP. After that, other biodegradable films appeared on the market, such as protein-based plastics, polysaccharides, polyethylene oxide, and polyvinyl alcohol.
