Barrier Films Are an Important Component Of Food Packaging

Barrier films are an important feature of food paper packaging, especially for thin plastic-based items. Because the efficacy of barrier films is important to the success of food packing, selecting the suitable type of film for your specific application is critical. To accomplish so, several variables must be considered.

Consider the oxygen transmission rate (OTR), which is a metric of the amount of oxygen can pass through a film. Because they have an absorptivity of 10cc or less, superior mechanical films are a preferred choice in most culinary applications.

High barrier film food packaging films:

There are several high-barrier films available, each with its own set of benefits for different sorts of food items.

For example, the highly adjustable ethylene vinyl alcohol (EVOH) barrier film has an OTR of only 0.6cc/m2 and may be utilized as a component or as a standalone packaging material, making it perfect for fish, poultry, and meat packing.

KPET is a laminate that is used on other films that is made by covering PET film with a soft saran laminate. It has outstanding gas, moisture, and vapor qualities, making it perfect for use in adaptable food packaging for dry foods, highly odoriferous commodities, and those that are susceptible to absorbing other scents.

Pouch bags are an effective type of packaging for a broad variety of items, and their ability to print high-quality printing across the whole surface of the sack makes them perfect for automated marketing. The barrier layers in the bag are another significant advantage of choosing this style of packaging. Barrier films are designed to retain items in a variety of ways, including:

Odor protection: Using at least one layer of film allows aromas to be fully excluded from dry food, coffee, and other items even when the goods are on the shelf.

Moisture: Vapor and moisture may be a serious problem for bread, granola, and other mold-prone food. Barrier films, as opposed to inexpensive plastic packaging that just employs one thin layer, really keep mold spores away from the goods.

Some products can be damaged by sunlight and other thermally sensitive things to degrade. We can design creative food packaging that takes this into account.

Lower cost: Barrier film bags are less expensive for a variety of reasons because they require fewer materials.

  • Food Waste Avoidance

Poor packaging is responsible for 50% of total food waste worldwide, according to an FAO/UN assessment. This is due to the fact that media reportage of oxygen or moisture absorption might create unfavorable responses from farm to plate. Barrier films dramatically prevent food spoiling. This also seals in the inner aromas and keeps the food fresher for longer. As a result of these considerations, many meat producers have resorted to barrier films, which have certainly shown to be incredibly useful in the food sector.

  • Increased Product Purity

When product purity is required, high-barrier foil liners outperform ordinary films. Moisture and oxygen barrier liners keep environmentally sensitive or perishable items fresh for at least two years, far outlasting flexible packaging without high-barrier protection.

In multi-layer combinations, various flexible packaging resins, foil, or metalized polyester are employed.  However, because of its flexibility, availability, and efficacy as a barrier material, it has grown into an essential substance in its own right.

  • Capabilities for faster machining

Machining speed for high-barrier flexible films is considerably increased using metalized resins. Improved lamination technology and equipment minimize the chance of mistakes while also improving packing quality at quicker rates.

High-barrier flexible film packaging provides dependable quality and impermeable protection when combined with exceptional raw materials. The first liner off the production line is of the same high quality as the last. Because flexible films are both theoretically and practically flexible, they lend themselves easily to a broad range of bespoke designs.

Laminating film is commonly used in the FMCG business since it provides a few barriers against exterior factors while keeping the contents within intact and fresh for a long time.
