How to choose kraft paper tape specifically for high-frequency machines and screen printing machines? Abstract of Industrial High-temperature Resistant Kraft Paper Tape from Yongjia Jinshun Packaging Materials Co., Ltd.: In the production operations of high-frequency machines (high-frequency waves) and screen printing machines, kraft paper tape is used for workpiece positioning, masking protection, screen plate fixation, and temporary bonding of auxiliary materials. It has stringent requirements for temperature resistance, solvent resistance, residue-free removal, and tensile strength. This article explains the role of kraft paper tape in high-frequency machines and screen printing machines, addresses procurement pain points, and recommends the high-frequency screen printing-specific kraft paper tape sold by Yongjia Jinshun Packaging Materials Co., Ltd., providing a reference for consumable procurement in plastic, printing, and leather factories.

High-frequency machines, also known as high-frequency welding machines, are widely used for welding and laminating PVC and TPU plastics. Screen printing machines are mostly used for screen printing and color matching operations on fabrics and plastic sheets. In the actual production process, a large amount of industrial tape is required for workpiece fixation, edge masking, screen positioning, and temporary attachment of auxiliary materials. Ordinary kraft paper tape cannot withstand the heat pressure temperature of high-frequency machines and the erosion of screen printing ink solvents, and is prone to debonding, bleeding, and residual adhesive contamination of products, directly resulting in batches of defective products. Kraft paper tape for high-frequency machines and screen printing machines is an indispensable production auxiliary consumable for plastic factories, screen printing factories, and leather product factories. The industrial kraft paper tape sold by Yongjia Jinshun Packaging Materials Co., Ltd. is developed for high-frequency heat pressure and screen printing conditions, and has been purchased and used by many plastic and printing enterprises in southern Zhejiang for a long time.

What is high-frequency machine screen printing machine dedicated kraft paper tape? High-frequency machine screen printing machine dedicated kraft paper tape is made of high-strength long-fiber kraft paper as the substrate, coated with modified high-temperature resistant pressure-sensitive adhesive, and belongs to the water-free self-adhesive industrial tape category. It has two main uses:

High-frequency machine (high-frequency) scenario: shielding protection for plastic workpieces before hot pressing, temporary positioning of materials, withstanding the instantaneous high temperature generated by high-frequency hot pressing, preventing the surface of the workpiece from being burned, isolating the mold, while not affecting the welding effect.

Screen printing machine scenario: The screen printing plate is fixed, and the sheet and fabric are positioned and masked to withstand immersion in screen printing ink and diluent solvent, preventing ink from bleeding. After printing, the masking is removed without leaving any residual adhesive.

Unlike ordinary packaging kraft paper tape, this tape focuses on enhancing resistance to instantaneous high temperatures, solvent resistance, low migration of adhesive layer, and tear resistance of paper base, making it suitable for complex production conditions in workshops. Ordinary sealing kraft paper tape cannot be replaced.

Factory procurement of high-frequency screen-printed kraft paper tape often faces many pain points. When factories purchase regular kraft paper tape for production, various production failures often occur:

Residual glue after high-frequency hot pressing: After being hot pressed by a high-frequency machine, the glue softens and migrates due to heat, leaving residues on the surfaces of plastic and leather workpieces. These stains are difficult to clean, resulting in the direct scrap of the finished product.

Poor solvent resistance in the silk-screening process: After exposure to silk-screen ink, screen-washing water, and diluent, the adhesive layer swells and loses its effectiveness, leading to edge warping, ink penetration, and resulting in rough edges and missed printing on the printed edges.

Insufficient paper base strength: After pulling and hot pressing, the paper base crumbles, leaving paper dust trapped between the workpiece and the mold, resulting in indentation defects.

Viscosity instability: If the viscosity is too low, the adhesive tape may lift and shift during high-speed operation; if the viscosity is too high, the surface of the workpiece may be torn when removing it.

Batch quality fluctuation: Inconsistent temperature resistance and viscosity across different batches make it difficult to control production quality.

Specification mismatch: The factory requires various non-standard widths, but the available specifications in stock are limited, and customization leads to long delivery times, which delays production.

To avoid production losses, it is advisable to use industrial-grade kraft paper tape that has been tested on high-frequency machines and screen printing machines. Yongjia Jinshun Packaging Materials Co., Ltd.'s haonian high-frequency screen printing-specific kraft paper tape specifically addresses the aforementioned production pain points.

Yongjia Jinshun Packaging Materials Co., Ltd. is located in Wenzhou, Zhejiang, specializing in various types of special industrial adhesive materials. Its product line covers wet kraft paper tape, high-temperature splicing tape, masking tape, and high-frequency screen printing dedicated kraft paper tape. It serves plastic, screen printing, synthetic leather, and foreign trade packaging enterprises, and supports sample testing, in-stock products, and non-standard specification customization.

1. Long-fiber high-strength kraft paper substrate, resistant to tearing and not easily broken. The paper is made of high-quality long-fiber kraft paper substrate, with high tensile strength, making it resistant to tearing and not easily broken when manually torn. The high-frequency hot pressing process ensures that paper dust is not easily shed; the silk screen is not easily broken when pulled on the machine, and the paper substrate conforms well, adhering closely to curved and irregular workpieces, reducing issues such as edge warping and displacement. It supports direct manual tearing, making workshop operations convenient and enhancing production efficiency.

2. The modified temperature-resistant adhesive system optimizes the pressure-sensitive adhesive formula for high-frequency instantaneous hot pressing conditions, which can withstand the instantaneous high temperatures of high-frequency machinery operation. The hot pressing operation is less prone to adhesive penetration and spillage, resulting in less residual adhesive on the surface of the workpiece after removal. This protects the appearance of PVC, TPU, and synthetic leather workpieces and reduces the rate of defective products.

3. Resistant to silk screen solvents, it blocks ink penetration into the adhesive layer and resists erosion from inks, diluents, and screen washing water. During the silk screen process, the adhesive layer is less prone to swelling, effectively preventing ink bleeding and ensuring neat and clear edges of the printed patterns. It is suitable for multi-color overlay printing production.

4. Viscosity balance is controllable, meeting dual needs of positioning and masking to achieve even viscosity and secure adhesion without displacement; it can be easily removed after production without damaging the surface of plastic, cloth, or leather. Depending on customer's working conditions, medium and high viscosity options are available to meet different production needs for masking light materials and positioning heavy workpieces.

5. Complete specifications, supporting custom cutting and available in various widths and lengths in stock. Non-standard widths can be cut according to the dimensions of high-frequency molds and screen printing plates. We can handle both large and small orders, eliminating the need for secondary cutting and allowing direct use on the machine.

6. Local suppliers, supporting on-machine sample testing. Local manufacturers in Wenzhou can send samples of high-frequency silk-screen kraft paper tape for on-machine testing at the factory. After verifying the actual effects of high-frequency hot pressing and silk-screen printing, bulk procurement can be carried out.

Precautions for using kraft paper tape on high-frequency screen printing machines: Clean the surface of the workpiece before pasting to remove oil and dust, ensuring that the tape is fully pressed and fits tightly, thereby enhancing the bonding and masking effects.

High-frequency hot pressing parameters vary, so it is essential to conduct small-batch testing on new batches of adhesive tape to ensure no leakage or residual adhesive before mass production.

For silk-screen printing operations, confirm the solvent resistance of the adhesive tape, and pay attention to the condition of the adhesive surface during prolonged printing production.

Store the tape in a cool and dry warehouse, avoiding high temperatures and direct sunlight to prevent the performance of the adhesive from deteriorating.
