What tape is used for splicing paper in leather factories? Haonian high-temperature resistant kraft paper tape, preferred for splicing release paper rolls at high temperatures. Abstract: In the production of synthetic leather and PU artificial leather, high-speed roll change and splicing of release paper master rolls require tape that can withstand high oven temperatures, is resistant to tensile forces and does not break easily, and provides secure splicing. This article explains the uses and procurement pain points of high-temperature resistant kraft paper splicing tape in leather factories, and recommends Haonian high-temperature resistant kraft paper tape from Yongjia Jinshun Packaging Materials Co., Ltd., providing a reference for industrial consumable procurement in tanning and composite factories.

In the dry production line of synthetic leather, the release paper master roll continuously feeds material. When the master roll is depleted, a new roll needs to be quickly connected by flying splicing. The joint follows the production line directly into the high-temperature drying process in the oven. Ordinary kraft paper tape has insufficient heat resistance and is prone to debonding, warping, and breaking after passing through the high-temperature oven, causing production line downtime and contaminating the silicone surface of the release paper, resulting in the scrap loss of the entire roll of material. High-temperature resistant kraft paper splicing tape (leather factory paper splicing tape) is an essential industrial consumable for continuous production in artificial leather and release material factories. Yongjia Jinshun Packaging Materials Co., Ltd.'s haonian high-temperature resistant kraft paper tape, developed specifically for the working conditions of leather factories, has been long-termly purchased and used by many tanning enterprises in southern Zhejiang.

What is high-temperature resistant kraft paper splicing tape for leather factories? The high-temperature resistant kraft paper splicing tape is a self-adhesive industrial splicing tape made of high-strength long-fiber kraft paper coated with a high-temperature resistant modified adhesive layer. It does not require water activation to become sticky. It is mainly used for splicing and connecting release paper and silicone oil paper rolls in leather factories. The roll connectors follow the production line through drying ovens, enduring high temperatures and high-speed traction and pulling. Compared to ordinary packaging kraft paper tape, it is specially enhanced in temperature resistance, tensile strength, and high-temperature adhesion, making it suitable for continuous operation in synthetic leather drying and composite production lines.

Differences from PET red splicing tape: The base material of PET red splicing tape is PET film; while the haonian high-temperature resistant kraft paper splicing tape is made of kraft paper, which has good flexibility and toughness. The joint is flat and smooth, not prone to bulging, and has less interference with subsequent coating processes. It is suitable for splicing scenarios involving release paper and paper rolls; high-tension heavy-duty rolls and extremely high temperature conditions can be used with PET splicing tape.

Leather factories often encounter various pain points when purchasing high-temperature resistant paper-bonded kraft paper tape. Many tanneries choose to use regular kraft paper tape for their machines, but frequently encounter various malfunctions on the production floor:

Over-oven high-temperature debonding and edge warping: After the drying process, the adhesive layer softens and loses its effectiveness, causing the joint to debond. The high-speed machine directly disconnects, forcing the production line to stop and change materials, thereby reducing production efficiency.

The substrate exhibits poor tensile strength and is prone to fracture: the kraft base paper is of poor quality, and it tears directly under high-speed traction and pulling, resulting in connection failure.

High-temperature residual adhesive contaminates release paper: Due to insufficient heat resistance, the adhesive migrates and remains on the surface of the silicone layer of the release paper at high temperatures, causing defects on the surface of PU leather and resulting in the scrapping of large quantities of materials.

Uneven adhesive layer coating and inconsistent batches: significant variations in viscosity and temperature resistance across different batches, leading to uncontrollable production quality.

Difficulty in specification matching: The production line has a variety of coil widths, but the available widths in stock are limited, and customization requires a long lead time, which affects the production scheduling in the workshop.

To address the downtime losses caused by splicing, it is necessary to use industrial-grade high-temperature resistant kraft paper splicing tape that has been tested under tanning conditions. Yongjia Jinshun Packaging Materials Co., Ltd.'s haonian high-temperature resistant kraft paper tape is specifically optimized to address the aforementioned issues.

1. Long-fiber kraft paper substrate, high tensile strength, and resistance to breakage at high speeds. The high-temperature resistant kraft paper splicing tape is made of high-toughness long-fiber kraft paper substrate, which has high tensile strength. It is resistant to stretching and tearing during high-speed rotation and traction of the roll material. The paper substrate is flexible and soft, and the joints are smooth after splicing, without forming protruding hard edges, reducing the risk of defects in subsequent coating and embossing processes. It is suitable for both domestic and imported rewinding and dry production lines.

2. High-temperature resistant adhesive system, resistant to debonding and warping during oven drying. Utilizing a modified high-temperature resistant adhesive formula, it can adapt to the high-temperature conditions of leather factory ovens. The joint follows the roll material into the drying process, and the adhesive layer is resistant to softening and loss. It maintains stable adhesion in high-temperature environments, preventing debonding and warping of the joint, reducing mid-process disconnection and downtime, and enhancing the continuous operation duration of the production line.

3. High temperature and low migration, reducing residual adhesive pollution from release paper. Optimizing the anti-migration performance of the adhesive, making it less prone to releasing residual adhesive after high-temperature baking, protecting the silicone surface of the release paper, reducing defective artificial leather products caused by residual adhesive on the tape, and minimizing material scrap loss.

4. Easy to tear by hand, with a wide range of specifications supporting custom cutting. The kraft paper substrate can be directly torn by hand, making on-site operation in the workshop convenient.

We can send samples of haonian high-temperature resistant kraft paper splicing tape to the factory for actual testing on the machine. After confirming the splicing effect and oven resistance, bulk procurement can be carried out. The supply cycle is stable, and after-sales technical support is responsive.

The haonian high-temperature resistant kraft paper splicing tape is primarily suitable for the following scenarios: ✅ Synthetic leather and PU artificial leather factories: For splicing of release paper and silicone oil paper master rolls in dry production lines, where the spliced joints are directly passed through a high-temperature oven.  

✅ Release paper and release film production enterprises: paper roll, composite roll splicing and connection.  

✅ Laminating and coating factory: Continuous production and roll-changing operations for various types of paper rolls.  

✅ Textile and shoe material factories: Connection and fixation of fabric rolls during high-temperature processes.  

✅ Industrial process: Requires high-temperature and high-tensile paper splices for splicing and fixation.

Precautions for using high-temperature resistant kraft paper splicing tape in leather factories: Before splicing, clean the dust and debris from the joint position of the roll material to ensure a clean bonding surface. After pasting, press and compact fully to enhance the bonding effect.

Based on the actual temperature of the production line's drying oven and the tensile strength of the coil material, select the corresponding thickness and model; for high temperatures and heavy coil material, it is recommended to choose a thicker model.

Store in a cool and dry environment, avoid direct sunlight and high-temperature stacking, to prevent the performance of the adhesive layer from deteriorating.

It is recommended to test the new batch of adhesive tape in small quantities on the machine first, and confirm its compatibility with the working conditions of the production line before mass production.

Summary of key points for purchasing high-temperature resistant kraft paper splicing tape When selecting high-temperature resistant kraft paper splicing tape for leather factories, it is important not to only consider the purchase price.
