Polystyrene foam pressure seal liners have become an essential packaging solution across cosmetics, pharmaceuticals, food, beverage, chemical, agricultural, and oil industries. As packaging demands move towards greater product safety, tamper-evidence, sustainability, and customization, South Korea's leading manufacturers and suppliers of pressure-sensitive foam seal liners command global attention. This comprehensive guide explores the key players in South Korea, technical product features, application trends, and OEM/ODM opportunities for international brands, wholesalers, and producers seeking reliable partners in high-performance packaging solutions.
Polystyrene foam pressure seal liners (often referred to as PS foam pressure sensitive liners) are packaging inserts designed to secure containers, preserving product integrity and extending shelf life. These liners feature a disk of polystyrene foam, with a specialized adhesive layer that forms a tight seal when compressed by the cap or closure. The application process is simple: the liner is inserted into the cap, and, upon closure, adheres firmly to the lip of the container, creating a barrier against moisture, air, or contaminants without the need for induction sealing equipment.[1][2]
Key Benefits:
- Tamper-Evidence: Provides visible protection against unauthorized access.
- Leak Prevention: Acts as a barrier to liquids and volatile contents.
- Extended Shelf Life: Prevents degradation from air or moisture.
- Ease of Use: No heat induction required, suitable for a wide variety of products including solids and pastes.
- Customizable Printing: Brands may customize liners with logos and product details for regulatory or marketing purposes.
South Korea is renowned for advanced manufacturing capabilities and consistent quality standards, making it a sought-after market for pressure-sensitive foam packaging solutions. The landscape comprises both large-scale OEM/ODM partners and specialized suppliers who serve international clients in food, cosmetics, pharma, and chemical verticals.
Young Plus Corporation stands out for its innovation in pressure-sensitive packaging. Their polystyrene foam pressure seal liners are composed of premium foam and pressure-activated adhesive, designed to adhere impeccably to container lips, ensuring freshness and tamper-resistance. The firm's multi-industry versatility lets brands from cosmetics to chemicals benefit from secure packaging made for global distribution.[1]
Sung Won Industry Co., Ltd. produces PSP liners (pressure sensitive polystyrene) crafted with wax-coated, foamed polystyrene. These liners activate under screw cap pressure, even at low torque, making them compatible with a wide array of container materials including PE, PET, glass, and metal. Sung Won's capabilities include custom thicknesses and surface printing for regulatory compliance and international branding.[3]
Founded in 1996, Pacific Industry Co., Ltd. has established itself as a premier provider of foam liner materials and extrusion technology.

Polystyrene foam pressure seal liners are disk-shaped packaging inserts made of foam and pressure-sensitive adhesive. When placed inside a cap and screwed onto the container, the liner adheres to the mouth of the container, creating an airtight and tamper-evident seal. This process does not require induction sealing equipment and is ideal for both solid and paste products.[2][3][1]
Common sectors include cosmetics, pharmaceuticals, food and beverage, agricultural products, chemicals, oil and lubricants. These liners are chosen for their ability to protect product integrity, prevent leaks, extend shelf-life, and provide tamper-evidence across diverse packaging applications.[3][4][1]
Yes, most Korean manufacturers offer comprehensive OEM/ODM services that allow for custom sizes, thicknesses, and printed designs on the liners. Customization supports regulatory requirements, product identification, anti-counterfeiting, and marketing goals for global distribution.[4]
Key considerations include supplier experience, quality certifications, production capacity, turnaround time, customization options, and post-sales services. Reviewing export record and requesting samples for compatibility testing are recommended before placing large-volume orders.[1][4]
Recent advances involve eco-friendly foams and adhesives, smart printing with QR codes or tracking features, vented liners for sensitive products, and multi-layer constructions for added security. Korean suppliers also focus on rapid prototyping and advanced automation for cost-efficient, scalable solutions.[3][4]
