Shanghai developed a self-supporting bag making machine

Shanghai Light Industry Equipment Group Corporation Light Industry Machinery Factory has recently developed a SDL400 automatic bag making machine that can produce self-supporting bags. In addition to producing self-supporting bags, the machine can also produce self-sealing bags and three-sided bags. The bag has high positioning accuracy, high bag making speed, good tension control, stable material discharge, low noise, and stable performance. The finished bag has a smooth appearance, a good appearance and a beautiful appearance. High sealing seam strength is an ideal alternative to imported products in the flexible packaging industry. According to reports, the new products developed by the plant in recent years, the main performance indicators have reached the level of international products of the same type.

Common kitchen tasks include cutting food items to size, heating food on an open fire or on a stove, baking, grinding, mixing, blending, and measuring; different utensils are made for each task. A general purpose utensil such as a chef's knife may be used for a variety of foods; other Kitchen Utensils are highly specialized and may be used only in connection with preparation of a particular type of food, such as an coffee spoon or an coffee tamper. Some specialized utensils are used when an operation is to be repeated many times, or when the cook has limited dexterity or mobility. The number of utensils in a household kitchen varies with time and the style of cooking.

A partially overlapping category of tools is that of eating utensils, which are tools used for eating (c.f. the more general category of tableware). Some utensils are both kitchen utensils and eating utensils. Cutlery (i.e.spoon and other cutting implements) can be used for both food preparation in a kitchen and as eating utensils when dining.
