Shanghai Tangke Vacuum Bags: Empowering the Lychee Industry and Collaborating for a Shared Freshness Future

When the lychee season arrives, the market demand for lychees experiences explosive growth. However, the characteristic of lychees - "changing color in one day, aroma in two, and taste in three" - poses a significant challenge to the industry, making preservation a difficult problem to overcome. In the past, traditional ice pack preservation methods were extremely limited in effectiveness. Lychees were not only prone to discoloration and flavor changes due to oxidation but also faced a high spoilage rate, imposing immense operational pressure on large - scale fruit distributors and chain supermarkets.

Today, Shanghai Tangke New Material Technology Co., Ltd. has launched its revolutionary vacuum bags. With breakthrough innovative preservation technology, these bags have successfully broken the deadlock and emerged as the most reliable partners for numerous leading enterprises in the industry.

（As of today, Shanghai Tangke's products have developed several series, including Vacuum Sealer Bags, Laminated Films, Ton Bags, and Aluminum Plastic Composite Bags, with promising prospects for the future.）

Shanghai Tangke's Vacuum bags stand out with their unique craftsmanship. Through a special manufacturing process, they can precisely vacuum - pack lychees and quickly freeze them to minus 30 degrees Celsius using advanced freezing technology. In this perfect combination of extreme low temperature and vacuum environment, air is completely isolated, and the freshness of the lychees is, metaphorically speaking, "paused," allowing for long - term and perfect preservation. Compared with traditional ice packs, the advantages of Shanghai Tangke's vacuum bags are clear at a glance. Ice packs can only reduce the temperature to a certain extent and fail to effectively isolate air, making lychees highly susceptible to oxidation. This results in discoloration of the pulp, a significant reduction in the original sweet flavor, and a substantial loss of nutrients. In contrast, Shanghai Tangke's vacuum bags fundamentally solve these problems. By effectively isolating air, they greatly slow down the deterioration rate of lychees. Even after long - term storage and long - distance transportation, lychees can still maintain a plump appearance, delicious taste, and fully intact nutritional components

Currently, Shanghai Tangke has reached strategic cooperation agreements with many leading domestic fruit supply chain enterprises. A large - scale fruit wholesaler covering more than 20 provinces across the country revealed that after adopting Tangke's vacuum bags, the spoilage rate of lychees during cross - regional transportation dropped from 28% to 4%, reducing direct economic losses caused by preservation issues by over ten million yuan annually. Moreover, with the high - quality lychees preserved by these vacuum bags, the enterprise has successfully entered high - end supermarket channels, increasing the premium capacity of each lychee by 30%.

From the tree to the table, Shanghai Tangke's vacuum bags serve as a sturdy and efficient quality bridge, closely connecting fresh lychees with consumers. In the future, Shanghai Tangke New Material Technology Co., Ltd. will continue to deepen its exploration in the field of preservation technology. Guided by the principle of customer - oriented demand, the company will collaborate with more leading enterprises in the industry, jointly explore new frontiers in lychee preservation, and continuously inject new vitality into the lychee industry.
