Low Initial Temperature CPP

Low initial temperature CPP film is an important branch within the family of casting polypropylene films. It is specifically designed to enhance packaging production efficiency and reduce energy consumption. Its core feature is that it can achieve rapid and secure heat sealing at relatively low temperatures.


The low initial temperature CPP film achieved the comprehensive goals of efficiency improvement, energy consumption reduction, quality enhancement and cost optimization by simply lowering the key parameter of heat sealing temperature on the packaging production line, thereby triggering a "domino effect".


It is an indispensable key inner material in modern high-speed, automated and intelligent packaging production, fully reflecting the trend of the soft packaging industry towards greater efficiency and environmental friendliness.

Main Performance Features of Low Initial Temperature CPP Film

Achieve the maximum packaging speed

This is its core value. A lower unsealing temperature means that the heat sealing knife can complete the "heating-cooling" cycle more quickly, enabling the packaging machine to operate at its maximum speed and significantly increase production capacity.

Remarkable energy-saving effect

The heat sealing energy consumption is roughly proportional to the square of the working temperature. Therefore, reducing the heat sealing temperature can directly and significantly save electricity and reduce production costs, aligning with the carbon neutrality goal.

Perfect protection for heat-sensitive products

For chocolate, high-end ice cream, certain cheeses, and yogurt products, high temperatures are "enemies". The low unsealing temperature CPP can minimize heat transfer to the greatest extent, ensuring that the product's flavor, shape, and quality are not affected by the packaging process.

Excellent sealing quality

Avoiding the excessive contraction, deformation, or "burning" of the film at the sealing area due to excessively high temperatures, the seal becomes smoother, more beautiful, and more secure, reducing the scrap rate caused by sealing issues.

Extended equipment lifespan and reduced maintenance

The lower working temperature reduces the accumulation of dirt on the heat sealing knife, reduces the heat load on the heating elements, thereby extending the equipment's lifespan and reducing downtime for cleaning and maintenance.
