A craft brewery in Hamburg, Germany, experienced an off-flavor in its beer due to corrosion of the weld seams in its stainless steel tanks. Initially, the brewery suspected a problem with the raw materials and brewing process, testing each batch of materials but finding no issues. When the problem reached a stalemate, technicians entered the tanks and discovered corrosion and discoloration at the weld seams on the inner wall. These corrosion points, caused by prolonged immersion in acidic beer, had broken down the calcification film on the stainless steel at areas of poor weld quality. This allowed metal ions to dissolve into the beer, accelerating the oxidation of hop resins and producing the off-flavor.
To prevent a recurrence of this stainless steel weld corrosion-related beer spoilage, the German brewery searched globally for alternative materials and ultimately chose our food-grade 4*8ft 8mm thick HDPE sheets. This perfectly addressed the customer's pain point. Its surface is as smooth as a non-stick coating, as inert as glass, and can be molded into any seamless shape like plastic. Furthermore, the corrosion-resistant properties of HDPE sheets mean they are impervious to chemical cleaning agents, perfectly solving the problem of beer spoilage caused by corrosion of the inner walls of steel tanks.
With HDPE-lined milk tanks and storage tanks, the smooth, non-absorbent surface of the HDPE sheets allows for easy cleaning with a water gun, saving energy, reducing costs, and preventing cross-contamination.
Additionally, in food processing plants, customers can use HDPE sheets to create work surfaces, adhesive boards, and transport carts, ensuring a consistently high standard of hygiene in the working environment.
BEYOND's HDPE sheets, with their more hygienic, safer, and more economical approach, have become the preferred choice for modern food processing plants. This represents not only an upgrade in materials but also an evolution in production philosophy, earning BEYOND the favor and trust of consumers worldwide.
