In 2026, the global sublimation paper market is expected to reach USD 664 million, with roll products accounting for approximately 56.9% of the market and textile applications representing around 51%. As sublimation printing continues to move toward continuous, roll-to-roll and industrial-scale production, sublimation protective paper is becoming increasingly important as a supporting consumable for blanket protection and excess dye management.
Sublimation protective paper is placed between the fabric and the roller or printing blanket. It absorbs excess dye that is not fully absorbed by the fabric, helping protect heat transfer equipment while reducing image contamination, ghosting and other printing defects.
Hanrun Paper specializes in the R&D, manufacturing and supply of digital printing materials and equipment, providing customers worldwide with an integrated solution covering sublimation transfer paper, protective paper, printing equipment and heat transfer equipment.
For industrial sublimation production lines, protective paper may be a relatively niche consumable, but it plays an essential role in maintaining stable and reliable production.
The core principle of sublimation transfer printing is to use high temperatures to convert dyes in the transfer paper into a gas, allowing them to migrate into polyester fibers and other suitable substrates.
In actual production, however, not all of the dye can be fully absorbed by the fabric. This is especially common in the following situations:
✅High-ink-volume designs
✅Dark or highly saturated graphics
✅Large areas of solid colors
✅Continuous roll-to-roll production
✅Direct printing or high-ink-volume transfer
✅Fabrics with limited ink absorption
✅Improper matching of transfer pressure, temperature or printing speed
Some dye may pass through the fabric or escape around the edges of the printed design and come into contact with the equipment blanket. This can result in permanent contamination.
Sublimation protective paper helps absorb residual dye released during the transfer process, preventing dye buildup and contamination on the blanket. This helps maintain stable operating conditions and can extend the service life of the equipment blanket.
Founded in 2009, Hanrun Paper specializes in the R&D and production of sublimation paper and related digital printing materials. We offer protective paper in a range of GSM weights, materials and widths to meet different production requirements.
Hanrun Paper provides a wide range of protective paper specifications. The following are some commonly used options:
| Product | GSM | Recommended Applications | Key Advantages | Standard Widths |
|---|---|---|---|---|
| Protective Paper 18g | 18–19 GSM | High-speed textile production, such as fashion apparel, sportswear, cycling wear and high-volume flag fabric | Lightweight construction provides efficient heat transfer and is suitable for production lines focused on high-speed operation | 100–1900 mm |
| Brown Protective Paper 19g | 20 GSM | — | — | 1150 / 1600 / 1620 / 1650 / 1700 mm |
| Protective Paper 30g | 30 GSM | Apparel printing, banners and soft signage | A versatile, general-purpose option that offers a good balance between stability and dye absorption for most conventional textile and decorative transfer applications | 1600 / 1800 mm; maximum 2.6 m |
| Brown Protective Paper 30g | 30 GSM | — | — | Up to 3.25 m; no fixed width limitation |
Based on extensive practical production experience, Hanrun Paper recommends selecting protective paper slightly wider than the sublimation printing paper.
Common matching examples include:
✅1118 mm sublimation paper → 1200 mm protective paper
✅1500 mm sublimation paper → 1700 mm protective paper
This additional width provides better coverage and helps reduce the risk of dye contamination reaching the equipment or blanket edges during transfer.
For industrial sublimation production, simply meeting the specified GSM is not enough.
During wide-width, continuous production, unstable paper tension or insufficient material uniformity can lead to:
✅Wrinkling
✅Paper wandering or misalignment
✅Loose rolls
✅Paper breaks
✅Uneven paper density
✅Unstable machine operation
During the converting process, Hanrun Paper uses automatic tension-control slitting equipment and magnetic powder clutches to control slitting and rewinding tension. This helps reduce inconsistent roll tightness, wrinkling and other issues.
At the same time, Hanrun manages product specifications, technical documentation and batch traceability to maintain consistency between different production batches for long-term customers.
Hanrun Paper can also provide relevant technical documents such as TDS and MSDS, as well as FSC-related certification, helping customers meet different environmental and supply-chain requirements in various markets.
Sublimation protective paper is a paper-based material, so its storage environment can directly affect the condition and performance of the paper.
Hanrun Paper recommends the following storage practices:
The recommended shelf life is one year. Storage conditions should be maintained at approximately 10–30°C and 45–55% RH to minimize the impact of temperature and humidity fluctuations on the paper.
With an integrated portfolio of digital printing materials and equipment, Hanrun Paper provides more than protective paper. Our product range also includes sublimation paper, sublimation ink, printers and heat transfer equipment.
We can recommend suitable consumable combinations based on your equipment specifications, production speed, transfer paper width and application requirements.
Hanrun protective paper is available in multiple GSM options and extra-wide formats, with quality control covering raw materials, production, slitting, tension control and batch management.
If you provide your equipment model, paper width, target GSM and monthly consumption, Hanrun Paper can recommend a more suitable protective paper specification and provide a professional digital printing solution covering consumables and equipment.
