Vacuum Forming Tray Wide Range Of Applications

Vacuum Forming Tray Wide range of applications

Although the tray is only a small piece of equipment, but because the tray has an important convergence function, a wide range of applicability and pivotal joint, in handling, storage, transportation and packaging and other logistics aspects of efficiency, are in the center Position, so the size of the tray is the size of the package, the size of the compartment, the size of the container unit size. Only to the tray size as the standard, the decision packaging, truck compartment, train cars, container boxes and other supporting specifications and specifications of the series specifications, only to best reflect the loading and unloading handling, storage, transportation and packaging operations of the rationality and efficiency. In addition, the size of the Xiamen tray also involves the size of the container unit, the container size of the unit also involves the packaging unit size, truck compartment, rail truck compartment, warehouse access and cargo size, and even related to the logistics Infrastructure, railway stations, ports, terminals and other cargo handling and handling of the structure of the structure, loading and unloading equipment, the standard size. In a sense, the standardization of the pallet is not only a prerequisite for tray leasing, pallet circulation and recycling, but also a decisive factor in the mechanization and automation of loading and unloading handling, packaging, transportation and storage operations, without the uniformity of the tray size The serialization of the related facilities, equipment, devices and tools based on the pallet can only rationalize the local logistics and make it difficult to rationalize the whole logistics. In the international standardization of pallet size, as early as 1947 Sweden took the lead in the introduction of the tray standard, in 1961 the International Organization for Standardization issued ISO / R198 tray standard, it is recommended to use 0.8m × 1.2m, 0.8m × 1m, 1m × 1.2m3 The size of the ISO / R329 pallet standard, an increase of 1.2m × 1.6m, 1.2m × 1.8m two sizes; in 1971 and promulgated the ISO / TC51 tray standard, an increase of 0.8m × 1.1m, 0.9m 1.1m, 1.1m × 1.1m 3 sizes, and later, ISO / TC51 decided to cancel ISO / R198 and ISO / 329, recommended by 0.8m × 1.2m, 1m × 1.2m, 1.016m × 1.219m three sizes Alternative. As of 1997, 1.140m × 1.140m, 0.8m × 1.2m, 1m × 1.2m, 1.1m × 1.1m, 1.016m × 1.219m, 1.140m × 1.140m size by the International Standardization Organization (ISO) Recognized. On the international standards of trays, the International Organization for Standardization is also discussing the changes.

 In the use of a variety of plastic recycling methods for recycling of waste plastics, most of the need for plastic sorting. As the plastic consumption channels and more complex, and some consumption of plastic and difficult to distinguish it through the appearance of simple, therefore, it is best to identify the material on the plastic products. China has developed GB / T16288-1996 "Plastic Packaging Product Recycling Mark" with reference to the labeling of materials proposed and implemented by the American Plastics Association (SPE). Although the above-mentioned marking method can be used to facilitate sorting, there are many unmarked Of the plastic products, to the sorting difficult, for the different varieties of plastic, respectively, in order to classify the recovery, we must first master the identification of different plastic knowledge.

The following describes the simple plastic identification method:

      The appearance of the plastic by observing the appearance of plastic, can be a preliminary identification of plastic products belonging to the categories: thermoplastics, thermosetting plastics or elastomers. General thermoplastics are crystalline and amorphous. Crystalline plastic appearance is translucent, opaque or opaque, only in the film state was transparent, hardness from soft to horny. The amorphous form is generally colorless and is completely transparent when no additive is added, and the hardness is hardened from the horny rubber (this is often accompanied by additives such as plasticizers). Thermosetting plastics are usually filled and not transparent, and are transparent if they are not filled. Elastic body with rubber-like feel, there is a certain degree of stretch.
