Barrier films: Essential component of food packaging

 Barrier films: Essential component of food packaging

Barrier films are an essential component of food paper packaging, particularly for thin plastic-based products. Because the effectiveness of barrier films is critical to the success of food packaging, it is critical to choose the correct sort of film for your particular application. Several variables must be considered in order to do so.

To begin, consider the oxidation transfer rate (OTR), which is a measurement of how much oxygen a film allows to clear through it. Superior mechanical films are just a popular choice in most food applications because they have an absorption capacity of 10cc or even less.

Other important considerations involve film gauge, clarity, & barrier level, the type of food being packaged, and whether additional features, such as UV protection or odor prevention, are required. You should also think about the converting process to see how easy it is to cut the film & bond the edges.

Food Packaging Films with a High barrier film

There is a wide variety of high barrier films available, each with its own set of advantages for various types of food products. The extremely configurable ethylene vinyl alcohol (EVOH) boundary film, for example, has an OTR of only 0.6cc/m2 and can be used as a material or as an independent packaging material, making it ideal for fish, poultry, and meat packaging.

KPET, a laminate used on other films, is created by coating PET film with a soft saran laminate. It has excellent gas, moisture, and vapor properties, making it ideal for use in adaptable food packaging for dry goods, highly odoriferous goods, and items sensitive to absorbing other odors.

Pouch bags are an excellent form of wrapping for a wide range of products, and the ability to print custom high-quality printing also on entire earth of the bag makes them ideal for automatic marketing. One of the other major advantages of using this type of packaging is the barrier films that are in the bag. Barrier films are built to keep products in different ways, including:

  • Odor protection: To use more least 1 layer of film allows odors to be completely excluded from dry food, latte, as well as other products even during storage although the product is on the shelf.
  • Moisture: Vapor & moisture is sometimes a major issue for bread, granola, and any mold-prone product. In contrast to cheap plastic packaging that it only uses one thin layer, barrier films truly keep mold spores away from the product.
  • Sunlight can damage some products and also heat up packaging, causing chocolate as well as other thermally sensitive items to spoil. We can create innovative food packaging which it takes this into consideration.
  • Lower cost: Because barrier film bags need fewer materials, they are less expensive for a variety of reasons.
  • Preventing Food Waste

According to an FAO, United Nations report, poor packaging is responsible for 50 percent of total food waste worldwide. This is because media coverage of oxygen or moisture absorption can start causing undesirable reactions from farm to plate. Food spoilage is significantly reduced by barrier films that act as either a protective layer against chemicals, moisture, and gases. This also keeps its inside aromas sealed and the food fresher for a longer time. As a result of these factors, many meat companies have turned to barrier films, which have unquestionably proven to be extremely beneficial within food industry.

Bopp adhesive tape are widely used in the FMCG industry because they provide a few barriers against external elements and keep the contents inside intact and fresh for a prolonged period of time.
