HMPSA
HMPSA (Hot Melt Pressure Sensitive Adhesive) is a specialized type of hot melt adhesive that remains permanently tacky after cooling. Unlike standard hot melts that form a rigid bond, HMPSA provides consistent, repositionable adhesion with light pressure, making it ideal for labels, tapes, hygiene products and various industrial applications.
Formulated with a precise balance of flowability and flow resistance, HMPSA creates strong, durable bonds by fully wetting the adherend surface. At room temperature, it reaches 50% of its ultimate bonding strength within 20 minutes, 90% within 24 hours, and full 100% strength after 72 hours, ensuring reliable long-term bonding performance for critical applications.
At Adhesive (Shanghai) Co. Ltd, our HMPSA is manufactured to meet strict international performance standards, featuring exceptional initial tack, long-lasting holding power, and wide temperature resistance. It is the preferred choice for industries requiring consistent, high-efficiency pressure-sensitive bonding solutions.

Unique Selling Points
- Cost Efficiency Through Vertical Integration
- In-House Raw Material Production: By synthesizing polymers, tackifiers, and plasticizers internally, we eliminate middlemen costs, offering HMPSA at 20–30% lower prices than competitors
- Bulk Customization: Tailor formulations for specific substrates (e.g., glossy films, low-surface-energy plastics) without minimum order quantity (MOQ) constraints
- Superior Performance
- Instant Bonding:Forms firm, permanent bonds within seconds under light pressure, perfectly compatible with high-speed automated production lines to boost efficiency
- Versatile Substrate Compatibility:Adheres strongly to challenging surfaces including coated paper, PE/PP films, automotive composites, and nonwoven fabrics
- Temperature Resilience:Maintains stable tack and bonding strength in extreme cold (-40°C) and high heat (80°C), suitable for refrigerated logistics, automotive under-hood applications, and outdoor use
- Eco-Friendly Formulations
- Low VOC & Solvent-Free: Compliant with EU 10/2011 for food-contact applications
- Bio-Based Options: HMPSA with up to 75% renewable content for sustainable packaging and hygiene products
Production Process
We adopt a streamlined, quality-centric manufacturing workflow to produce high-standard HMPSA:
- Raw Material Synthesis:In-house production of polymers and resins using advanced polymerization reactors
- Precision Mixing:Uniform blending of ingredients in professional kneading machines, followed by viscosity and tack testing
- Degassing & Filtration:Vacuum treatment to remove air bubbles, ensuring defect-free adhesive films
- Pelletization & Cooling:Shaping into uniform pellets and rapid cooling to preserve product performance
- Packaging:Automated nitrogen-flushed packaging to prevent oxidation and extend shelf life
Applications
HMPSA is widely applied across global industries that demand reliable pressure-sensitive bonding, covering core sectors as follows:
- Packaging Industry
Ideal for BOPP packaging tapes, security seals, recyclable glass bottle wash-off labels, flexible packaging resealable lidding films, and logistics labeling, ensuring secure adhesion and easy application.
- Automotive
Used for spray-coated adhesive applications in automotive interior trim assembly, noise-dampening tape production, and component bonding, with rapid curing and durable performance for automotive manufacturing standards. - Nonwovens & Hygiene
Formulated to be soft and skin-friendly, suitable for disposable hygiene products like diapers and sanitary napkins, as well as medical tapes and bandages, ensuring safe, irritation-free use.
