Product Overview
1.Premium polyester mono filament with minimal stretch and low tension loss. Remains taut during long oval printing runs to prevent misregistration and ghosting.
2.Precision weaving ensures consistent mesh openings and even ink penetration. Sharp reproduction of fine lines and graphics with uniform ink deposit and stable color output.
3.Solvent-resistant polyester withstands repeated washing and re-stretching. 55T Mesh Resists filament breakage in cyclic printing, reducing downtime and replacement costs.
4.Various standard mesh counts in stock: low counts for thick ink & puff printing; high counts for fine graphics & thin water-based ink printing. Custom cut sizes to fit Bihong aluminum frames.
5.Optimized surface treatment provides superior glue bonding. The mesh adheres tightly to aluminum frames and prevents delamination in long-run production.
6.Resists printing inks, washout chemicals and de-coating agents. Simple ink removal allows repeated re-stretching, cutting consumable costs.

Compatible with all Bihong oval screen printing machines and Bihong aluminum screen frames. Widely used for T-shirts, hoodies, denim, kids wear, bags and footwear. Suitable for water-based ink, plastisol, high-density, discharge and puff printing.
Raw Materials
1. Substrate: PU synthetic leather, leather-like fabric, luggage cut pieces
2. Embossing die: Engraved brass / steel mold (custom concave-convex pattern, male die or matched male & female dies for deep texture)
3. Auxiliary: High-temperature release paper, protective film
4. Equipment: Flat hot embossing machine, hydraulic heat press, roller embosser (for continuous roll production)

Process Flow
1. Convert customer pattern / logo into artwork, engrave inverse concave-convex texture on metal die (brass / steel). Die precision directly decides texture sharpness.
2. Die surface polishing and trial test to adjust pattern depth.
1. Inspect PU / leather-like fabric cut pieces: Remove dust, oil stain. Check material thickness and surface coating.
2. Pre-condition fabric: Control material humidity. Too high humidity causes bubbling; too dry will lead to cracking during pressing.
3. Positioning: Mark embossing position on cut pieces, fix with locating jig to avoid pattern offset.
1. Mount engraved die on heat press head, set parameters for PU leather (Vietnam factory standard):
- Temperature: 110 ~ 130°C
- Pressure: 3 ~ 6 MPa
- Dwell time: 3 ~ 8 seconds
2. Run trial sample, check texture depth, clarity, rebound, surface burn mark. Fine-tune temperature / pressure / time before mass production.
1. Place cut piece flat on press base, align die with marked position. Release paper can be laid on top to prevent sticking.
2. Close press head, apply preset heat & pressure for required dwell time.
3. Keep pressure holding stage to reduce PU rebound.
1. Keep pressure applied while cooling (important for PU). Do not lift die immediately after heating.
2. Lift press head only after partial cooling. Leave cut piece to fully cool at ambient temperature.
1. Check items: Texture depth, pattern sharpness, position deviation, surface scorch, wrinkling, cracking, rebound after cooling.
2. Flex test: Bend PU part repeatedly to check if embossed area cracks or texture flattens quickly.
3. Repair or reject defective pieces.
Optional top coat (water-based protective varnish) spray on embossed surface to improve abrasion resistance and slow down texture rebound. Then fully cure before cutting and assembly.
- Rub fastness: Dry & wet rub test
- Flexing test: Repeated bend test (bag use scenario)
- Texture retention test: Check emboss depth after aging
Common Pain Points in Vietnam Bag Manufacturing
1. PU rebound: The biggest issue. Texture gradually fades after use; hence medium durability.
2. Over-temperature: PU surface burns, gloss mark, cracking on bending.
3. Insufficient pressure / short dwell time: Shallow, unclear pattern.
4. Material inconsistency: Different PU coating formula will lead to unstable embossing effect; same parameters may get different texture depth.
Two Production Modes in Vietnam Factories
1. Cut piece batch embossing (most common for bag factories): Flat hydraulic hot press, process individual cut pieces after cutting. Flexible for small batch & custom logo/texture.
2. Roll continuous embossing (large material suppliers): Roller emboss machine emboss full PU roll before cutting. High output for large volume orders.
