Toothpaste Tube

Composite Tubing Preparation
Production begins with the preparation of composite tubing. Through multi-layer structural composite molding, different functional layers are stably combined to form the basic soft tube body suitable for pharmaceutical use. The layers are uniformly bonded, the tubing is stable overall, and there is no delamination. No delamination or deformation will occur during long-term storage and use.

Tube Body Forming and Sizing Control
After the composite tubing enters the forming process, it is processed into a standard circular tube structure, and its size and shape are controlled to ensure that each batch of tubing maintains consistency in appearance and feel, ensuring a smooth filling process and reducing equipment adjustments and filling abnormalities.

Precise Cutting and Length Control
The formed tubing is automatically cut according to the set specifications, ensuring that each soft tube has a uniform length.
The cuts are smooth, the length error is small, and this avoids problems caused by length deviations affecting filling, sealing, or appearance consistency.

Tube Shoulder Forming and Mouth Fixing
The tube shoulder and mouth are firmly combined with the tube body through a molding process, which is a crucial step in the soft tube structure. This ensures that the tube mouth does not loosen or leak during repeated squeezing and capping.

Sealing Process
After filling, the soft tube is sealed at the bottom through a standard sealing process.
The seal is fully fused, flat, and secure. This affects the safety of the product during transportation, storage, and use, reducing the risk of seal failure and product returns.

In-Process Quality Inspection
Multiple inspection procedures are set up during the production process to confirm the appearance, structural integrity, and basic performance. This allows for timely detection of abnormalities, preventing problematic products from entering the next process, reducing batch risks, and improving overall stability.

Finished Product Inspection and Release
Before shipment, the finished products are uniformly inspected to confirm that they meet the established production standards before entering the packaging and shipping process.
