The silicone conveyor belts used in bag-making machines are industrial belts specifically designed for packaging equipment that operates under high temperatures, requires high precision, and must meet stringent hygiene standards. Below are the core features, application scenarios, common specifications, and purchasing recommendations for this product:
Silicone conveyor belts perform exceptionally well in bag-making machines (such as heat-sealing bag-making machines, non-woven bag-making machines, and gusseted bag-making machines), primarily due to the following characteristics:
High and Low Temperature Resistance: The operating temperature range typically spans -60°C to +200°C (with short-term exposure up to 250°C–300°C), making them ideal for the high-temperature environments of heat-sealing and cutting processes in bag-making machines. They will not deform or melt due to heat.
Anti-adhesion and Release Properties: The smooth surface provides excellent anti-adhesion properties. During heat sealing, molten plastic film does not easily adhere to the belt, ensuring a flat bag opening and reducing the frequency of downtime for cleaning.
Food-Grade Safety: High-quality silicone material is non-toxic and odorless, compliant with food contact standards (such as FDA and LFGB certifications), making it suitable for the production of food packaging bags.
Abrasion Resistance and Aging Resistance: It exhibits exceptional stability against ozone, UV radiation, and thermal oxidation, ensuring a long service life and resistance to cracking.
Flexibility and Precision: Typically manufactured as seamless loop belts, they operate smoothly without joint bounce, ensuring precise control over bag length.
Main Applications
Heat-sealing and cutting bag-making machines: Utilizes its high-temperature resistance and anti-adhesive properties to ensure no sticking at the seal.
Non-woven bag-making machines: Conveys non-woven materials for ultrasonic welding or heat sealing.
Continuous roll bag/vest bag machines: Stable conveying during high-speed operation.
Other packaging machinery: Such as pillow-type packaging machines, shrink wrapping machines, and other processes requiring heat-resistant conveying.
