Tianjin Paper Tubes : Environmentally Friendly Core Material for Support Packaging, Suitable for Multiple Scenarios

Tianjin paper tubes are tubular environmentally friendly materials made of paper through rolling and bonding. According to the forming process, they can be divided into spiral paper tubes (spiral winding type) and seamless paper tubes (flat winding type). With the core advantages of being lightweight and high-strength, cost-effective, recyclable and biodegradable, they have become an indispensable basic supporting product for many industries such as chemical fiber, film, printing, metallurgy, packaging, and construction, covering the needs of all scenarios from industrial production to daily life.

Accurate matching of product categories and application scenarios: In the chemical fiber industry, as a winding mandrel for fibers such as DTY, POY, nylon, and polyester, it needs to have high roundness (roundness error ≤0.3mm/m) and deformation resistance to ensure uniform fiber winding; in the film industry, it is suitable for BOPP, PET, PVC, and other film rolls, requiring stable winding tension (tension fluctuation ≤5%) to avoid wrinkling or stretching damage to the film; in the printing and papermaking industry, it is used as a support for roll printing, newsprint, and aluminum foil, and the surface needs to be flat and smooth (roughness Ra≤3.2μm) to prevent scratching the roll surface; in the metallurgical industry, it is used as the outer packaging for metal rolls such as aluminum plates and steel plates, and needs to have impact resistance (no damage or deformation after a 1m drop); in addition, it also includes special types such as medical device outer packaging (complying with GB 15980 sterile standard), battery sleeves (insulation resistance ≥10¹²Ω), and molten steel temperature measuring paper tubes (high temperature resistance ≥1000℃), meeting the functional requirements of special scenarios.

The production process balances environmental protection and quality: Raw materials are selected from recycled paper pulp or virgin wood pulp, combined with environmentally friendly starch adhesive or PVA adhesive (formaldehyde-free). The process involves pulping, slitting (paper width error ≤ ±0.1mm), winding (winding tension 5-10kN to ensure tight interlayer adhesion), drying (constant temperature drying at 60-80℃ for 30-60 minutes, moisture content controlled at 8%-12%), and precision cutting (length error ≤ ±1mm). Wall thickness (0.5mm-20mm), inner diameter (10mm-500mm), and length can be customized according to requirements. Products can be treated with wax impregnation and lamination to improve waterproof and corrosion resistance, or flame retardants can be added to achieve V0 fire resistance standards. Significant advantages of core technology: It is over 80% lighter than metal tubes of the same specifications, reducing transportation and storage costs; it is 100% recyclable, meeting the "dual carbon" target and reducing environmental impact; and it has a high degree of customization, matching the winding tension requirements of different roll materials, reducing roll material transportation losses.

When using and selecting materials, compatibility is crucial: heavy-duty roll materials (such as steel plates and aluminum plates) should use high-strength spiral paper tubes with a wall thickness ≥8mm and a compressive strength ≥1800N/m; waterproof paper tubes should be used in humid environments (such as outdoor storage) to prevent moisture absorption and deformation; food and medical device packaging should use food-grade raw materials and environmentally friendly adhesives to ensure no odor or release of harmful substances. After adopting customized high-strength paper tubes, a film manufacturer reduced its roll material transportation loss rate from 3% to 0.8%, lowered packaging costs by 15%, and simultaneously achieved full recycling of packaging waste, resulting in a dual improvement in environmental and economic benefits.
