Engineered for Critical Industries

JSD provides advanced Euro Cap and TPE solutions across a wide range of application areas, including pharmaceuticals, food & beverage, and cosmetics. We ensure safe, high-performance packaging at scale.

Large-Volume Parenteral Products

Euro Caps: The ‘Sealing Guardian’ of Pharmaceutical Packaging

TPE Euro Caps are produced using advanced co-injection molding technology, which allows one, two, or multiple polymer materials to be molded simultaneously into a single, fully integrated cap within a precision mold. Compared with traditional combination caps manufactured through injection-molding and compression-molding processes, Euro Caps offer higher material purity, enhanced biosafety, and superior drug compatibility.

Co-injection molding technology also enables the development of more complex structural designs, resulting in less dimensional deviation, improved consistency, and greater product stability. Moreover, by effectively preventing foreign-particle contamination and silicone-oil residue, as well as by ensuring better sealing performance, no particle shedding during puncture, and zero leakage during needle withdrawal, Euro Caps significantly improve patient safety and reduce overall risks associated with medication use.

Euro Caps are widely used in large-volume BFS and FFS infusion packaging. Owing to their outstanding cost-performance advantages, they are rapidly becoming the mainstream solution within the industry.

Other Pharmaceutical Products

Euro Caps: The ‘Safety Guardian’ of Medical Packaging

Medical-grade TPE Euro Caps serve a dual purpose: facilitating drug delivery while ensuring patient safety. The cap material must exhibit exceptional chemical inertness, purity, compatibility, and biosafety, while also maintaining stable performance under a wide range of mechanical stresses. Additionally, in certain medical applications, highly precise dimensions and carefully engineered structures are required to meet stringent usage requirements.

Medical-grade Euro Caps are produced using advanced co-injection molding technology, which allows one, two, or multiple polymer materials to be molded simultaneously into a single, fully integrated cap within a precision mold. The cap's inner layer must feature exceptional chemical inertness, purity, and compatibility to ensure biosafety, while the outer layer must be engineered to maintain stable performance under a wide range of mechanical stresses.

This design guarantees sealing integrity, protects the purity of medications, and adheres to the strictest regulatory requirements. Additional user-focused features include easy-open functionality and anti-tampering protection. Currently, Euro Caps are widely used in large-volume infusion therapy, clinical injection procedures, and various diagnostic applications.

Food & Beverage

Euro Caps: The ‘Quality Guardian’ of Food Packaging

Euro Caps for food packaging are manufactured using precision co-injection molding technology, which allows two or more polymer materials with distinct functionalities to be layered in a molten state and seamlessly fused into a single, fully integrated cap. This design provides a range of key benefits, including excellent barrier properties, chemical resistance, reliable sealing, and integrated features such as anti-tampering and anti-counterfeiting protection.

Euro Caps are applied in food packaging to ensure food safety, enhance consumer experience, and convey brand value. Their use aligns with the industry trend toward greener and more sustainable packaging. Through material optimization, euro caps can be designed with a lighter weight, thus improving cost-effectiveness.

Cosmetics

Euro Caps: The ‘Beauty Guardian’ of Medical Aesthetic and Cosmetic Packaging

Euro Caps and TPE products are widely used in the packaging of medical aesthetic products and cosmetics. They embody a seamless fusion of technology and design, combining the rigorous standards of the pharmaceutical industry with a strong commitment to delivering exceptional consumer experience. These packaging solutions strike an optimal balance between cost-efficiency and visual appeal. Just as medical aesthetic products and cosmetics enhance the beauty of the user, their packaging must likewise reflect elegance and beauty.

Modern medical aesthetic products and cosmetics often contain highly active and sensitive ingredients, such as peptides, hyaluronic acid, and growth factors. Their packaging must therefore meet the highest biocompatibility standards to ensure product stability. To achieve this, the cap's inner lining must provide low adsorption and minimal leaching, while the outer layer must deliver an extraordinary tactile and visual experience through a refined matte texture and a luxurious appearance.

TPE Euro Caps are widely used in the packaging of medical aesthetic products and cosmetics, from daily skincare to professional skin rejuvenation treatments. Their smooth, hydrophobic inner walls enable precise dispensing and easy operation, making them suitable for a wide range of applications. Typical uses include the packaging of high-performance serums and ampoules, eye serums, luxury face creams, single-use vials, freeze-dried powders, and professional salon products—all of which demand safe, reliable packaging designed for effortless use.
