PET TWIST TIE: Industrial Packaging and Everyday Storage
READ MORE >
The core consumer value of roasted nuts (such as cashews and almonds) lies in their crisp texture and rich flavor, and maintaining these two values hinges on preventing oil oxidation. From the single perspective of oxidation protection, tin ties are an indispensable core protective component in roasted nut packaging. Their absence directly leads to accelerated oxidation and deterioration of the nuts, completely destroying their core quality.
Roasted nuts have a fat content as high as 45%-60%, of which unsaturated fatty acids account for over 70%. These components are highly susceptible to oxidation reactions with oxygen in the air. In packaging scenarios without tin ties, even using composite films, kraft paper bags, and other packaging materials can only achieve basic wrapping and cannot form a durable and stable airtight barrier. When nuts are opened and taken out, the sealing structure of the packaging is broken, allowing oxygen to quickly enter the bag and initiate the oil oxidation process. First, this causes the nut flavor to deteriorate, with the original nutty aroma gradually being replaced by a rancid taste. Then, the texture changes from crisp to astringent and soft, losing its core nutritional value. Simultaneously, the peroxides produced during oxidation can destroy nutrients such as vitamin E and even pose health risks. Under room temperature storage conditions, roasted nuts without tin ties oxidize and deteriorate significantly faster, rapidly shortening their shelf life.
More importantly, roasted nuts are often consumed in small portions multiple times. The lack of tin ties means that effective resealing is impossible. After each use, the remaining nuts are exposed to oxygen and moisture for extended periods, accelerating oxidation and deterioration, and easily attracting dust and impurities. Professional tin ties, with their strong metal bonding properties, precisely seal the bag opening after the initial sealing and subsequent openings and closings, forming a tight seal that effectively blocks oxygen intrusion, slows down oil oxidation, and stably extends the shelf life of the nuts' crisp texture and rich flavor.
Twist-HD's tin tie series is custom-designed to protect baked nuts from oxidation. Made of food-grade rust-resistant metal, its width precisely matches the specifications of various nut packaging bags, providing a strong seal and smooth opening and closing. Choose our tin tie to build a solid line of defense against oxidation for the core quality of your baked nuts, safeguarding product value and consumer trust.
