With the exquisite techniques, innovative crafts and large scale production line, Hicap Closrues provides clients with high quality packaging closures and services,not only strengthening the pilfer proof function, but also make the whole packaging to be more premium.
Wine Screwcaps (30x60, 31.5x60, 30x44, 25x43, Tin Saran liner, Saranex liner)
Hicap Closures Wine screwcaps have been adopted by leading wine manufacturers in many coutries due to the benefits they offer with respect to traditional corks: they have no impact on the organoleptic qualities of the wine, avoiding oxidation and the so-called `cork taint`.
The wine lasts longer over time and its delicate balance does not change when transported.
Hicap Closures screwcaps make the bottle easier to open and to re-seal, maintaining the quality and the taste of the wine for longer. The screwcaps can be personalised with a variety of decoration techniques to meet the customer`s brand and marketing requirements.
Spirits Closures (33x57, 33x47, 31.5x44, 31.5x50, 28x38, 30x60, 28x18, 36x52 FDA, food grade etc.)
Hicap Closures is the world leader in the production of non-refillable closures and in anti-counterfeiting technologies, with 10 billion closures sold each year.
Technological innovation has provided spirits manufacturers with packaging solutions that make the counterfeiting of packaging increasingly difficult, enabling them to protect their brand image.
Current solutions encompass an infinite number of non-refillable pourers with different levels of protection; non-refillable valve systems and tamper-evident systems.
We are able to design totally customised closures in an infinite range of colours, shapes, sizes and materials to meet the needs of customers and to enhance brand image.
Oil and Water Closures (31.5x24, 31.5x44 safety closures FDA)
Hicap Closures provides a diversified range of caps, both short and long, with pourers that have been specifically designed for the viscosity of the oil, with a view to enabling perfect pouring, as well as anti-drip devices to avoid the drips that could form when pouring is interrupted.

Vacuum freeze-drying technology basic research needs to be strengthened (1)
Vacuum freeze-drying is a sophisticated process that begins by freezing wet materials or solutions at low temperatures, typically between -10°C and -50°C. Once frozen, the material is placed in a vacuum chamber where the pressure is reduced to between 1.3 and 13 Pascals, allowing the ice to sublimate directly into vapor without passing through the liquid phase. This method effectively removes moisture while preserving the structural integrity of the product. As one of the world's largest producers of Active Pharmaceutical Ingredients (APIs), China has significant potential for adopting this technology. However, despite its rapid development in recent years, the foundational research behind vacuum freeze-drying remains underdeveloped compared to more mature markets. Additionally, there is a shortage of skilled professionals in this field. The high initial investment required for freeze-drying equipment, along with relatively high energy consumption and production costs, also limits its widespread adoption. Therefore, enhancing basic theoretical research, ensuring drug quality, and reducing production costs have become critical challenges for the advancement of this technology.
One of the key advantages of vacuum freeze-drying is its ability to maintain the physical and chemical properties of heat-sensitive materials. Because the process occurs at low temperatures, it minimizes degradation and preserves the active components of the product. The resulting dried material is highly stable, making it ideal for long-term storage. Moreover, since the material is dried in a frozen state, its original structure and appearance are largely retained. Unlike other drying methods, vacuum freeze-drying avoids surface hardening, creating a porous, sponge-like texture that allows for quick rehydration. This makes it particularly useful in pharmaceutical and food industries where reconstitution is essential. Another benefit is the minimal risk of chemical or biological changes during the process, as the environment is both cold and nearly air-free. This helps preserve color, aroma, and potency, especially in sensitive compounds.
To improve the efficiency and application of vacuum freeze-drying, researchers are focusing on strengthening the fundamental understanding of the process. While the equipment has advanced significantly in China, the theoretical foundation still lags behind international standards. Current studies emphasize the analysis of key parameters such as temperature, pressure, and material characteristics, as well as the mechanisms and optimization of the drying process. Understanding these factors is crucial for improving system performance and reducing costs. Research also involves determining the physical properties of materials, such as thermal conductivity and mass transfer coefficients, and how environmental conditions like humidity and pressure affect them. Process parameters, including refrigeration, heating, and material form, are being studied to optimize the freezing and drying stages. Ultimately, developing a solid theoretical framework will support the sustainable growth of vacuum freeze-drying technology in China and beyond.
