Packaging plays a crucial role in preserving the quality and freshness of products. At CapeCup, we’re always on the lookout for innovative packaging solutions that meet the needs of a variety of industries.
One such solution is our new triple-layered seal pouches, made with paper, PET (polyethylene terephthalate), and PP (polypropylene). Let’s have a closer look at how it keeps its contents fresher for longer.
Triple layered paper, PET, and PP seal packaging provides superior sealing capabilities that safeguard the contents against moisture, oxygen, light, and other external factors that could compromise product integrity. Each layer brings its unique set of advantages to create a robust packaging system.
The Paper Layer
The outermost layer of the triple-layered packaging is composed of paper, which provides strength and durability. Paper serves as a protective barrier against physical damage, while also offering an ideal surface for printing branding information and product details, enhancing the overall aesthetic appeal of the package.
The PET Layer
The middle layer of PET acts as a moisture and oxygen barrier. PET is known for its excellent transparency, high tensile strength, and resistance to punctures, making it an ideal choice for food and beverage packaging. Its exceptional barrier properties help to preserve the freshness, flavour, and aroma of the contents, extending their shelf life.
The importance of the moisture barrier
The PET layer acts as a barrier against moisture, preventing the absorption or release of water vapor. This feature is especially crucial for perishable food items, snacks, and beverages, as it prevents them from becoming stale or losing their crispness.
The importance of the oxygen barrier
Oxygen can cause oxidation, leading to spoilage and degradation of products such as food, pharmaceuticals, and sensitive chemicals. The PET layer effectively blocks oxygen ingress, preserving the freshness, taste, and potency of the contents.
The PP Layer
The innermost layer of the packaging is made of PP, a flexible and heat-resistant material. PP ensures an airtight seal, preventing any leakage or contamination. It also offers good chemical resistance, making it suitable for a wide range of products, including pharmaceuticals, cosmetics, and industrial goods.
Keeping Contents Fresh
Triple layered paper, PET, and PP packaging is great for maintaining the freshness and quality of sealed contents due to their combined properties. It also offers excellent light-blocking capabilities, safeguarding light-sensitive products like beverages, oils, and medications. Protection from UV radiation helps maintain the quality, colour, and potency of the sealed contents.
All in all, this packaging system offers an ideal balance of strength, durability, moisture resistance, oxygen barrier, and light protection, making it an excellent choice for various industries, including food and beverage, pharmaceuticals, and cosmetics.
Our triple-seal pouches are available in a variety of sizes.
