March 04,2022

Thanks to food packaging film has the excellent performance of efficient protection of food safety, and its high transparency can effectively beautify the packaging, it in the position of commodity packaging is more and more important. In order to meet the current changing external environment and the needs of different consumers, many enterprises in the world have increased the research and development of food packaging film.


In this paper, we will introduce the types of food packaging films.

General Packaging Film


Currently, the commonly used food packaging films are PVA coating layout barrier film, bidirectional stretch polypropylene film (BOPP), unidirectional stretch polypropylene film (OPP), bidirectional stretch polyester film (BOPET), nylon film (PA), flow polypropylene film (CPP), aluminized film and so on. These films are widely used because of their excellent performance of good transparency, high tensile strength, a certain gas and water resistance and low production cost. Generally, some coffee cups for take-out use this general packaging film. And some tea cups usually use plastic bubble sealing film.


Edible Packaging Film


Edible packaging film refers to the film formed by edible materials, mainly lipids, proteins, polysaccharides and other natural macromolecules, adding edible plasticizers, crosslinking agents, etc., through physical mixing, through different processing technologies. According to the characteristics of the main raw materials used, edible membrane can be divided into four categories: sugar edible membrane, protein edible membrane, lipid edible membrane, composite edible membrane. For edible functional film, it has been widely used in daily life, such as glutinous rice paper used on the familiar candy packaging, corn baking packaging cup packaging ice cream and so on, they are typical edible packaging.


Antibacterial Food Packaging Film


Antibacterial food packaging film is a kind of functional film with the ability to inhibit or kill bacteria on the surface. According to the forms of antibiotics, they can be divided into two types: direct antibiosis and indirect antibiosis. Direct anti-bacteria is achieved through direct contact between packaging materials containing antibacterial ingredients and food. Indirect anti-bacteria is mainly to add some substances to the carrier to adjust the micro-environment in the package, or to control the growth of microorganisms by using the selective permeability of packaging materials, such as air-controlled packaging film.


Nano Composite Packaging Film


Nanocomposite thin film refers to the composite thin film material formed by the dimension and size of the nanometer order of magnitude (1-100nm) components embedded in different matrix, which has the advantages of both traditional composite materials and modern nanomaterials. Caused by nano composite film because of its special structure of surface effect, volume effect, size effect and so on makes their optical properties, mechanical properties, antibacterial properties, the respect such as blocking performance present the characteristics of conventional materials do not have make it has been widely used in food packaging, not only can meet the requirements of extend the shelf life of food, Also able to monitor changes in the quality of the food in the package.


In Conclusion


Packaging film is more and more popular and it has many different types for specific uses. If you are looking for good quality packaging film, you can find it in Shantou Kaixuan Packaging Co. Ltd. It specializes in various food packaging films and there are many are for sale, such as coffee cup packaging film, plastic bubble tea cup sealing film.
