Design and Application of Heat Seal Waterproof Paper

2024-10-16

Heat sealable waterproof paper can combine the basic structure of paper with waterproof and heat sealing functions. The paper base material is made of high-quality natural fibers, such as wood pulp or recycled pulp, to ensure that the paper has sufficient strength and toughness. At the same time, according to different application requirements, the thickness of the paper is also different, which can be used for food packaging or high-strength packaging in industry.


Design and Application of Heat Seal Waterproof Paper


Heat sealable waterproof paper is coated with a waterproof coating such as polyethylene (PE) or polypropylene (PP) on the surface to have waterproof properties. It also adopts a double-sided coating design to ensure that the paper has comprehensive waterproof protection during transportation and storage. In addition, the paper also has a breathable design, which allows gas exchange while being waterproof, which is particularly suitable for some food packaging scenarios.


The design of the heat seal layer uses low melting point polymers such as EVA or LDPE. These materials can quickly form a strong seal through heat and pressure to ensure the safety of the package contents. The sealing temperature and time are precisely designed to ensure that it is suitable for common packaging equipment and provide a fast and reliable sealing effect.


At the same time, the surface of heat-seal waterproof paper has been specially treated to have good printability and support various printing methods and customized designs, such as brand logos, color patterns, etc. In addition, it has the advantages of being recyclable or biodegradable, which is suitable for industries with high environmental protection requirements, such as food and medical packaging.

Heat sealable waterproof paper is specially coated to achieve heat sealing and waterproofing functions.


Main features of heat sealable waterproof paper:

Waterproof coating:

Paper is treated or coated to effectively resist water penetration, making it ideal for packaging products that need to be moisture-proof, such as food, medical supplies or electronic products.

Despite its waterproofness, the paper can still be printed and customized, which is convenient for brand promotion and packaging design.


Environmental protection:

Heat sealable waterproof paper is made of recyclable or biodegradable materials and meets environmental protection requirements.

In industries that reduce plastic waste, it is an ideal choice to replace plastic packaging.


Strength and durability:

Heat sealable waterproof paper has high tensile strength, ensuring that it is not easy to tear or lose its protective ability during transportation, storage and handling.

It can resist puncture and abrasion, suitable for packaging sharp or fragile items.
