Engineered wood flooring trends include the following:
1. Environmental protection materials: With the improvement of people's awareness of environmental protection, more and more consumers choose to use environmental protection materials. Engineered wood flooring is a combination of wood and man-made materials. Compared with solid wood flooring, the wood used is more economical and can reduce the cutting of natural forests.
2. High-quality appearance: Engineered wood flooring has the natural beauty and texture of solid wood flooring, and it can also create more diversified appearance effects through processing technology. Consumers are increasingly demanding the appearance of the floor, Engineered wood flooring can meet their needs for high-quality appearance.
3. Durability and wear resistance: Engineered wood flooring adopts a multi-layer structure to make it have high durability and wear resistance. This makes it suitable for use in high-traffic areas such as kitchens and hallways in commercial premises and homes.
4. Convenient installation and maintenance: Engineered wood flooring is more convenient to install than solid wood flooring. It can be installed by locking system or adhesive, reducing installation time and cost. At the same time, Engineered wood flooring is also easier to maintain than solid wood flooring, and only needs regular cleaning and maintenance.
5. Diversified design and color choices: Engineered wood flooring provides a rich variety of design and color choices to meet consumers' needs for personalization and customization. From classic wood grain design to modern stone and metal grain design, consumers can choose the right floor according to their own preferences and home style.
In general, the popular trend of Engineered wood flooring is to develop in the direction of environmental protection, high quality, durability, convenient installation and maintenance, and diversified design and color selection. These trends reflect changes in consumer demand and preferences for flooring.

Because of the heat-sensitive problem of raw materials for foods, that is, poor heat resistance, some foods that cannot be produced by conventional canning methods can use this new patented processing technology and a new filling line for aseptic filling to produce qualified products. High temperatures and oxygen are important factors that affect the taste, color, and nutritional value of finished food products. Now, this new ABC line has been successfully researched and designed to ensure that the shelf-life of the products it produces meets the required 12 months at room temperature, and that the product will not undergo any microbial spoilage and deterioration during this shelf life. ?
In 1999, the project was jointly studied by Ball Packaging Europe, Mennen Ding Food and Serac. In the same year, the research and design of the aseptic filling production line for this beverage can with an annual production capacity of 5 million cans was completed. This new study has successfully proved the fact that full-layer cans can be aseptically filled even if they do not meet or meet the high requirements for the production of high-quality products. This ABC operation has been successfully used at Campina InternaTionae for the commercial production of products such as milk beverages. The filling rate is 100 cans per minute and 20 million cans have been filled so far. ?
The so-called aseptic filling is a process in which a sterilized beverage is filled in a pre-sterilized container under aseptic environmental conditions and then the packaging container is sealed in a clean room (clean room). For this reason, the following bottleneck (difficulty) problems can be anticipated immediately. During the filling process and after filling, the product is not heat-sterilized. Moreover, products must be free of spoilage bacteria and must be refrigerated. ?
Therefore, control and proper hygiene management during processing under such manufacturing environment conditions are very important. The cleanliness of filling and container-sealing environments must also maintain an absolutely hygienic state as one of the necessary conditions. Sterile filling is very different from the traditional high temperature autoclaving after filling. Now, the polyester bottle line set up by France's Refresco has used this aseptic filling system. ?
The core part of the ABC flow line is Serac's filling system. The metal can consists of the can body and the lid part. After being washed, the can body must be sterilized with 210% dry heat. Since the silicone coating of three-piece cans is not resistant to high temperatures, it cannot be handled at this temperature. For this purpose, another method, high-frequency induction heating, was used to perform thermal sterilization of cans at 160°C. ?
The can body is filled with a beverage pre-sterilized with an ultra-high temperature (UHT) sterilization method in an ultra-clean room. The sterile liquid nitrogen is then immediately injected into the headspace of the can. A drop of liquid nitrogen immediately changes to nitrogen occupying the entire headspace, with the purpose of isolating the contamination and attack of oxygen and bacteria. Then it is sealed with a can roll sealer. Usually this type of sealing opportunity is used to form excessive air flow, which is likely to cause the risk of secondary pollution. Now they have carried out the research and development of a new process sealer. However, after the process of filling and filling with liquid nitrogen, the seam sealing process is performed immediately, which can reduce the risk of this secondary pollution to zero. ?
Liquid nitrogen fills the top gap with three major functions. Prevents pollution, excludes oxygen from the headspace, and forms a certain rigidity by giving an internal pressure to the can; Compared with PET bottles, metal cans do not allow oxygen and light to penetrate, so it is possible to extend the shelf life of products for at least 1 year, during which time To prevent changes in the product's sensory quality; as with paper containers, cans are more robust and are more suitable for use in the vending machine sales industry. Recycling is also convenient. Metal cans are these characteristics that appeal to consumers. ?
Although the cost of the ABC production line is at the same level as the HPHT line and the aseptic PET bottle line, the cost of the can itself is lower than that of a heat-resistant PET bottle. This kind of beverage is very popular in the United States because of its healthy image to people; it is still in a period of less mature markets in Europe; the latest refrigerated coffee cans in Germany and southern Europe have emerged; Japan has more than 8.6 billion cans annually market.
The world's most advanced two-piece aseptic filling
The world's most advanced full scale two-piece canned beverage filling line has been successfully developed in Europe. Set this line to Refresco Holding. The collaborator of the research and design project is a global company consisting of Ball Packaging Europe and Refresco. The latest products produced by this line were listed at the end of 2005. ?
