Product Overview
The Sandwich Packaging Belt Strapping Production Line is designed to produce high-quality packaging belts from recycled or new materials. Featuring a high-precision extrusion system, this line ensures minimal errors in belt dimensions. With a user-friendly interface, the machine is perfect for manufacturers aiming for consistent, reliable output while maintaining energy efficiency.
Advanced Production Flow for Superior Strapping Belts
The Sandwich Packaging Belt Strapping Production Line is built to deliver precision and efficiency. Its process starts with the feeding of recycled or new PP materials, which are mixed, pre-dried, and melted. The high-precision extrusion system ensures consistent output, forming the belt embryo, which is cooled and shaped. The dual stretching phases improve the belt’s tensile strength, followed by optional printing and embossing for customization. This complete process guarantees the production of durable, uniform packaging belts.
High-Precision Engineering for Quality and Efficiency
This Packaging Belt Manufacturing Machine excels in its ability to deliver consistent quality. Equipped with a high-precision screw, it ensures excellent plasticization, hardness, and wear resistance. The belt’s width and thickness are accurately controlled, minimizing errors and meeting industry standards. The advanced CNC Packaging Belt Cutting system ensures every belt is produced with perfect dimensions, reducing wastage.
Versatile and Eco-Friendly Production
Zhongrui's packaging belt production line supports both new and recycled materials, making it environmentally friendly and cost-effective. The PP Belt Stretching Process ensures that the belts are strong and durable, suitable for various packaging needs. Its energy-efficient design ensures minimal power consumption while maximizing output, providing long-term operational savings.
Feature of PP strap making machine
Versatile Material Usage: Supports recycled and new PP materials, offering flexibility and cost savings.
Precision Extrusion: High-precision screw ensures uniform belt dimensions and excellent plasticization.
Dual Stretching: Enhances the strength and durability of the packaging belts through primary and secondary stretching.
Embossing and Printing: Offers customization options with embossing or printing for personalized strapping belts.
CNC Cutting: Ensures accurate belt length and width for consistent quality.
Process flow of PP packing belt production line
Feeding: Raw materials, such as recycled or new PP materials, are loaded.
Stirring: The materials are mixed thoroughly.
Pre-drying: Ensures moisture removal from materials before further processing.
Melting and Measuring Extrusion: Materials are melted and extruded through a high-precision screw system.
Embryo (Belt Embryo) Cooling and Forming: The extruded belt embryo is cooled and shaped.
Oven Preheating: Preheats the belt for the stretching process.
Primary Stretching: Initial stretching to enhance the belt’s strength.
Secondary Stretching: Further stretching for desired thickness and width.
Embossing: Adds texture or markings; printing can be done before embossing if needed.
Oven Tempering and Setting: Ensures the belt’s durability and consistency.
Cooling: Final cooling of the formed strap.
Finished Product Winding: The finished product is wound and prepared for storage.
Tips: if you have a choose of printing that you can printing first and then embossing in the project.
How to Maintain
To maintain the optimal performance of your Sandwich Packaging Belt Strapping Production Line, regularly clean the machine's extrusion and cutting components. Lubricate moving parts as required, and ensure the belts and screws are inspected for wear and tear periodically. Always use high-quality materials to prolong machine life.
