What Types of Coating or Lamination Are Used with Paper Yarn Base Paper?

With the widespread application of environmentally friendly materials in home furnishing, packaging, wallpaper, curtains and home textiles, Paper Yarn Base Paper has become a new type of substrate favored by the high-end market due to its natural, light, breathable and biodegradable characteristics. However, in order to further enhance its mechanical properties, durability, moisture resistance and visual beauty, Paper Yarn Base Paper is often used with different types of coating or lamination processes.
1. Why does Paper Yarn Base Paper need coating or lamination?
Paper Yarn itself is made of natural plant fibers such as pulp and wood pulp, with a loose structure, strong hygroscopicity and a large surface friction coefficient. Without surface treatment, the following problems are likely to occur:
Water absorption and wrinkling, reduced strength
Surface fuzzing and easy to break
Difficult to print or dye, unclear patterns
Not stain-resistant, easy to fade
Rough touch, affecting the decorative experience
Therefore, coating and lamination treatment can significantly improve the wear resistance, waterproofness, color expression and hand comfort of paper yarn base paper, which is an indispensable and important link in practical applications.
2. Common coating types and their characteristics
1. Acrylic Coating
Features: transparent, flexible, environmentally friendly and non-toxic
Advantages: can improve surface smoothness, enhance printing suitability, and have certain waterproof function
Applications: wallpaper, curtains, decorative fabrics
2. Polyurethane Coating (PU Coating)
Features: wear-resistant, fold-resistant, and chemical corrosion-resistant
Advantages: improve surface elasticity and tensile strength, and feel soft
Applications: used for home surfaces that are frequently touched and scrubbed (such as sofas and cushions)
3. Flame Retardant Coating
Features: add environmentally friendly flame retardants
Advantages: meet the requirements of public spaces and commercial fabrics for fire protection standards
Applications: hotel decoration, conference halls, subway car interiors, etc.
4. Hydrophobic/Oleophobic Coating
Features: form a hydrophobic layer, repel water and oil
Advantages: improve anti-fouling performance, easy to clean and maintain
Applications: placemats, kitchen curtains, tablecloths
3. Common coating types and their uses
1. PE coating (polyethylene film)
Features: thin, transparent, low price
Advantages: waterproof and moisture-proof, increased flexibility
Applications: simple packaging, disposable decorative items
2. PET coating (polyester film)
Features: high strength, strong temperature resistance
Advantages: can effectively improve tear resistance, light resistance, and heat resistance
Applications: wallpaper, exhibition display cloth, composite curtains and other high-end fields
3. PVC coating (polyvinyl chloride film)
Features: thick, oil-proof, and strong anti-fouling properties
Advantages: can achieve surface embossing, leather texture and other decorative effects
Applications: suitable for high-end furniture finishes, floor decorations, curtain fabrics
4. Hot melt adhesive film/TPU film composite
Features: soft, good elasticity, can be hot-pressed and bonded
Advantages: no chemical adhesives are required, more environmentally friendly
Applications: clothing composite fabrics, home textile composite films, etc.
Coating and coating technology not only gives paper yarn base paper excellent functional performance, but also expands its actual application space in decoration, packaging, home, clothing and other fields. Choosing the right surface treatment method according to product needs and application scenarios is the key to improving product competitiveness and user experience.
In the future, as environmental regulations become stricter and consumers' preference for natural and sustainable materials increases, coating and laminating processes will also develop in the direction of "green, solvent-free, and water-based", bringing broader innovation space and market opportunities to the paper yarn-based paper industry.
