Fuliyuan's PVC fresh - keeping film machine is specially designed for the packaging and preservation of vegetables, fresh fruits, flowers, oil - free raw food, as well as daily necessities and industrial packaging. The screw is designed with special mixing function and high plasticizing ability, which ensures good plasticization and excellent mixing effect, so as to produce high - quality PVC fresh - keeping film to meet the preservation needs. At the same time, the equipment has a high output. It can be equipped with a fully automatic adjusting die head and an automatic thickness gauge with APC control, which can online automatically detect the film thickness and automatically adjust the die head, ensuring the uniform thickness of the fresh - keeping film and improving the product quality.

It is mainly used in the food packaging fields of microwave oven food heating, refrigerator food preservation, fresh and cooked food packaging in families, supermarkets, hotels, restaurants and industrial production. Similar to the PVC fresh - keeping film machine, the screw design ensures a good plasticizing effect. The cooling forming roller adopts a special spiral flow channel design, which can make the film cool and shape well even under high - speed production. The produced PE fresh - keeping film has appropriate toughness and transparency, meeting various food packaging needs.

Using LLDPE (linear low - density polyethylene) as the main raw material, it produces single - sided or double - sided adhesive two - layer or three - layer co - extruded stretch wrapping film with self - adhesiveness through extrusion. The co - extruded wrapping film produced has higher tensile strength, puncture resistance and impact resistance than the single - layer wrapping film, and also has good retraction memory and self - adhesiveness. It can be widely used in the containerized pallet packaging of bulk goods, which can effectively prevent the goods from falling, collapsing and dust pollution during transportation. For example, in the transportation packaging of goods in industries such as glass products, chemical building materials, hardware tools, electrical appliances, papermaking, plastics, ceramics, food, and beverages, the products produced by Fuliyuan's LLDPE stretch film and wrapping film machine can play an important role in improving logistics efficiency and reducing transportation losses.
