This category include double wall glass
The double-walled glass is basically a glass within a glass. The air between the two glasses is sucked out when it is made, creating a vacuum. Instead of having a heating or cooling element to keep drinks hot or cold, it is designed to keep beverages at the correct temperature by not allowing heat to escape or enter.
We offer a diversity of glassware products mainly including many types of Drinkware , Wine Glasses , Glass Vase , Glass Plates/Dishes, Glass Candle Holder, Storage Jar, wood product, ceramic, Rattan Wrapped Glass, and lots of other popular glass products on the market.

Liquid packaging in the post-processing of filling, distribution, storage, etc., must be sterilized by high temperature or frozen, so the inherent defects of the polyamide type table printing ink can not meet the requirements of liquid packaging, production of liquid packaging manufacturers of color printing Must be for different types of co-extruded PE film, non-polyamide type of printing ink, the most suitable liquid package ink in the market is polyester and modified products, single-liquid type and two-liquid reaction type Ink.
Since milk and beverages are for human consumption, packaging films, printing inks, etc. should also meet the hygienic standards for packaging materials and food packaging regulations. Therefore, the inks used for printing should be non-toxic, odorless, and have less residual solvents. Does not contain toxic heavy metals and other requirements. So as not to contaminate milk and drinks, and harm the health of consumers.
According to the above requirements for ink performance, it is necessary to select an ink with superior performance. The general printing is the use of two-component polyurethane type surface printing ink, and after the ink is printed, the gloss oil treatment is performed, the cost is relatively high and the process is cumbersome. At present, the more widely used and better quality is Chao Lifu 313A type surface printing ink and Chaolifu 314 type surface printing ink produced by Zhejiang New Oriental Ink Group Co., Ltd. It does not need to be separately treated with a varnish, but only in the printing ink. The addition of a quantitative hardener, after curing for 24 hours after printing, achieves both resistance to boiling, to hydrogen peroxide treatment, and to abrasion.
These two kinds of inks are special printing inks designed for milk and beverage packaging films, and have good affinity with polyethylene film, good glossiness of ink layer, high attachment fastness, heat resistance, oil resistance, and resistance Water-based properties are also excellent; it can be said to be ideal for liquid packaging film printing inks such as milk and beverages. Chao Lifu 313A ink is an alcohol-soluble polyamide ink that can withstand boiling below 100°C and can withstand hydrogen peroxide sterilization below 60%. Chao Lifu 314 printing ink is a two-reaction reactive polyurethane-modified ink, capable of resistance to 121 °C / 40 minutes retort sterilization, can withstand 80 °C, a concentration of 35% hydrogen peroxide sterilization. According to the oxidation resistance test of Chaolifu 314 two-liquid reactive ink, the printed film after 24 hours of aging was soaked in hydrogen peroxide solution at a temperature of 45°C to 50°C and a concentration of 35% for about 15 minutes. The ink has good adhesion and basically no discoloration. It can fully meet the requirements of liquid packaging such as milk and beverages.
Requirements for liquid flexible packaging inks
Liquid packaging films such as milk and beverages are usually printed by means of surface printing. Most of them are polyamides or modified into binders. These inks were first developed in gravure printing inks in China, and the production process is relatively mature and complete. This type of ink is suitable for polyethylene, polypropylene film, ink layer adhesion fastness, good luster; but the polyamide type ink Pu h has poor water resistance, not resistant to grease, not resistant to freezing and other performance defects. Printing of this type of ink in high-temperature summers tends to produce stickiness and softening, and freeze-up occurs during low-temperature winter printing.
