ALOX PET film is used for fresh corn packaging ALOX PET film refers to a type of PET (Polyethylene Terephthalate) film that has been treated with a layer of aluminum oxide (ALOX) coating. This coating provides various benefits to the film, including enhanced barrier properties against oxygen and moisture, improved heat resistance, and increased shelf life for packaged products. These characteristics make ALOX PET film suitable for packaging applications where preserving freshness and extending the shelf life of perishable goods, like fresh corn, are important considerations. The ALOX coating on the PET film creates a barrier that prevents oxygen and moisture from permeating through the film. This is particularly beneficial for fresh produce like corn, as exposure to oxygen and moisture can lead to spoilage, loss of flavor, and reduced quality. The enhanced barrier properties of ALOX PET film help maintain the freshness, flavor, and appearance of the packaged corn.

Constructing high-barrier packaging for refrigerated or frozen contents is crucial to ensure the quality, safety, and shelf life of the products. Here are some general recommendations for the construction of high-barrier packaging for refrigerated or frozen items: Material Selection: Primary Packaging Material: Choose materials with excellent barrier properties to prevent the penetration of oxygen, moisture, and other gases. Common materials include metallized films, aluminum foil, and high-barrier polymers such as ethylene vinyl alcohol (EVOH) or polyvinylidene chloride (PVdC). Secondary Packaging Material: Consider the overall packaging system, including the primary and secondary layers. Secondary packaging, such as cartons or boxes, should provide additional protection against external factors. Sealing Integrity: Ensure that the packaging has a reliable and airtight sealing mechanism to prevent the ingress of air, moisture, or contaminants. This is especially important for frozen items where maintaining a consistent temperature is critical. Cold-Resistant Adhesives and Inks: Use adhesives and inks that can withstand low temperatures without losing their integrity. This prevents issues like delamination or ink degradation during refrigeration or freezing. Pouch Design: Consider the design of the pouch or packaging to ensure ease of sealing and handling. The packaging should be durable and resistant to cracking at low temperatures. Venting and Gas Purging (MAP): For refrigerated items, modified atmosphere packaging (MAP) can be employed. This involves adjusting the gas composition inside the packaging to extend shelf life. However, this may not be suitable for frozen items where a completely sealed environment is often preferred. Shock Resistance: Packaging should be designed to withstand freezing temperatures without becoming brittle or prone to breakage. This is especially important for items that may experience rough handling during transportation and storage. Compliance with Regulations: Ensure that the packaging materials comply with relevant food safety and packaging regulations for refrigerated or frozen products. Labeling: Clearly communicate storage instructions on the packaging. Information such as "Keep Frozen" or "Refrigerate After Opening" should be prominently displayed. Testing and Quality Control: Conduct rigorous testing of the packaging under simulated storage and transportation conditions to ensure its performance in maintaining the desired temperature and protecting the product. Sustainability Considerations: Consider the environmental impact of the packaging materials and explore sustainable options without compromising on barrier properties.
