High barrier films play a pivotal role in safeguarding products against the detrimental effects of moisture and oxygen. These films often incorporate high-density polyethylene to ensure a robust moisture barrier packaging material, adept at maintaining the integrity of a pouch or bag.
Innovations in film foil laminations have further enhanced these products, providing an oxygen barrier packaging structure that is second to none in preserving freshness and extending product lifespan.
The synergy of multiple layers in high barrier films, including high density polyethylene, creates an impenetrable defense against external agents. Whether utilized for food, pharmaceuticals, or sensitive electronics, these materials are integral to an array of packaging applications that demand the highest protection standards.
Let’s learn more about the properties of high barrier films for moisture and oxygen protection.
As a high-barrier film manufacturer and exporter based in Qingdao, China, CloudFilm helps global converters, packers, and brand owners choose moisture and oxygen barrier films that match their product, line speed, and shelf-life targets.
What Are High Barrier Packaging Films?
High barrier packaging films are specialized materials designed to protect sensitive goods from degradation. These films incorporate protective layers and materials capable of creating a high moisture barrier, shielding items such as fruits and nuts, snack foods, and nutritional supplements from the detrimental effects of moisture and vapor.
Their ability to maintain the state and quality of products sensitive to moisture makes them a cornerstone of sustainable packaging.
These flexible packaging films are tailored to meet the specific packaging solution needs of various products. By combining high-barrier films with project details like design and functionality, manufacturers can ensure that their goods, especially those susceptible to spoilage, are well protected from environmental factors.
Typical high-barrier structures include transparent ALOx PET Film, PVDC-coated PVDC PET and co-extruded EVOH Film, often laminated with PE, CPP or aluminum foil to create complete moisture and oxygen barrier packaging.

Benefits of High Barrier Films
High-barrier films are essential in the food and beverage industry, providing a multitude of benefits that ensure product safety and longevity. These films offer superior protection against moisture and oxygen, contributing significantly to the preservation of taste, aroma, and nutritional value. The following are the main benefits of high barrier films:
Heat Tolerant
High barrier films are engineered to withstand elevated temperatures, a crucial attribute for products that encounter heat during transportation, storage, or display. The heat tolerance of these films ensures that the barrier properties remain intact, preventing the permeation of moisture and gasses that could compromise the quality of the contained goods.
Waterproof
Waterproofing is another key feature of high barrier films, ensuring that no moisture can infiltrate the packaging to damage the product inside. By repelling water, these films protect goods from humidity and accidental liquid exposure, which could otherwise lead to spoilage or reduced efficacy.
High Oxygen Barrier
One of the defining features of high barrier films is their ability to efficiently block oxygen transmission. By maintaining low oxygen transmission rates, these films prevent oxidative damage, preserving the freshness and quality of oxygen-sensitive products.
Puncture Resistant
Durability is a hallmark of high barrier films, and their resistance to punctures is a testament to their robust construction. The layers of materials used in these films are designed to withstand rough handling and the rigors of transportation, ensuring that the contents stay secure.
Heat Resistance
The heat resistance of high barrier films safeguards products during exposure to high temperatures, which can occur during processes such as sealing and sterilization. This characteristic ensures that the packaging does not degrade or lose its barrier properties when subjected to heat.
Encapsulation of Organic Devices and Compounds
High barrier films are also integral in the encapsulation of organic devices and compounds. These films provide a protective layer that shields sensitive materials from environmental factors, thus preserving their functionality and extending their usability.
Extended Shelf Life
One of the primary advantages of using high barrier films is their ability to extend the shelf life of perishable goods. By providing a formidable defense against moisture, oxygen, and other contaminants, these films slow down spoilage and maintain the quality of the contents for a longer period.
Excellent Printability
Aside from their protective properties, high barrier films offer excellent printability, allowing for high-quality graphics and branding to be applied directly to the packaging. This enhances the aesthetic appeal and marketability of the product, making it more attractive to consumers.
Applications of High Barrier Films in Food Industry
The use of high barrier films is instrumental in the food industry, where they meet the diverse packaging requirements and challenges through ongoing research and development. Their role in preserving non-food items, alongside food and non-food products alike, is equally important, highlighting their universal appeal and functionality.
The following are the main applications of high barrier films in the food and beverage industry:
- Meat and Poultry: High-barrier films with superior barrier properties are used to retain freshness and extend the product’s shelf life.
- Dairy Products: Sealed barrier systems in packaging ensure that dairy goods are protected from external elements.
- Coffee and Tea: Multi-layered structures, including ethylene vinyl alcohol, prevent flavor loss and maintain product quality.
- Bakery Items: Flexible pouches and food bags designed for baked goods reduce food waste by keeping items fresh.
- Frozen Foods: High-barrier lamination processes and dry goods packaging requirements are met to protect against freezer burn.
- Beverages: Film barriers are essential in beverage packaging to prevent contamination and preserve taste.
- Ready-to-Eat Meals: Heat resistance and packaging solutions are tailored to meet the convenience needs of consumers while ensuring food safety.
- Snack Food: Polyvinylidene chloride layers safeguard dry ingredient food items like chips against moisture, ensuring crispness.
