INSTRUCTIONS (1) BACKGROUND OF THE INVENTION The present invention relates to a partially-finished product, such as a different thickness sheet, based primarily on decomposition and/or composite starch. The product is expanded by an extrusion process which can be carried out using different treatment methods such as biodegradable products, and which can be formed at the outlet of the extruder head or in a subsequent process, and the product can be formed therefrom. The starch based products of the invention are particularly suitable for packaging. Up to now, the plastic materials used for packaging are, for example, polystyrene, polyurethane, polyethylene and polyphenylene. However, the discarding of these products opens up new prospects for starch-based materials because starch-based materials are biodegradable and come from renewable resources, especially in the vesicular fraction. Conventional techniques have shown various methods to form products based on vesicular starch, however, because of the natural nature and nature of the starch itself, it has been a problem to obtain vesicular starch-based products of desirable size and cell distribution, and With respect to the density of the partially completed product, the partially completed product of the regular state can be converted to a comparative product according to weight and work at an industrial rate, particularly with respect to product fragility at the joint. This is especially true for starch-based foams in the preparation of formed sheets and related molds. Especially in the market, there is no starch-based part of the continuous product, which can be used in industrial process modeling, with the ideal properties of size, cell distribution and density, so that the final product has resilience, especially in the junction area. Even after a successful bend. ------II — II —------ — Order --------- Line AW. (Please read the notes on the back and fill in this page.) This paper scale applies to Chinese national standards.

Invention Description (13) A plate of food, life expectancy is 30 days 'Used to package meat, dairy products, vegetables, eggs and fruits; as a very small-scale support for glass, plastic or metal packaging; as a container for fast food, such as hamburger, potato chips, etc.; as a multi-part Inter-food containers, such as lunch boxes, coffee cups, and other hot foods for fast food and meals. The product of the present invention is also used as a container for lightweight objects, especially for multiple compartments such as mobile phones and small electrical appliances. The disc has mechanical properties to avoid damage to containers such as compressed paper. In the case of foods intended for use in local or low-temperature sputum bodies, the mega-barrel can be pressured and/or coupled to withstand the desired liquid. Temperature foam or polyester film and / or cellulose acetate and / or starch or polymer Other layers. In particular, films in the form of aromatic-aliphatic polyesters can be used, in particular polyalkylene terephthalate adipates, alkylene butyl esters, polyalkylene succinic acids, polyalkylene sebacates, poly Alkene phthalate, polycycloalkylene dicarboxylic acid, especially polyhexyl dimethyl dicarboxylic acid, polycyclohexyl dicarboxylic acid. If there is a need to absorb liquid, such as packaging meat, it can be considered directly The superabsorbent material inserted into the sheet is placed on the surface or in the middle of the two intershell layers or in the lower layer of the film which makes the packaging sheet impermeable to the packaging. Products formed into ovens and microwave ovens are also considered to be the subject of the present invention and may be characterized by a water repellent wrap to avoid drying of the container during cooking.
