Special cast film multi-layer co extrusion production line
Views: Date:2024-02-22

主图CPP.png

The CPP/CPE casting film production line adopts single machine or multi machine co extrusion methods to produce single-layer or multi-layer co extruded casting films, and can also use multipliers to achieve the production of 200+laminar casting films. All imported metering pumps and digital precise control of material percentage achieve precise input of special materials and reduce costs.

EVOH multi-layer co extruded high resistance diaphragm production line: EVOH is the most widely used high resistance material with high resistance to water vapor, oxygen and other purposes, which can be used for food packaging, electronic product packaging, etc. The conventional structure includes five or seven layers of co extruded high resistance diaphragm PP (PE)/ADH (EVA)/EVOH (PA)/ADH (EVA)/PP (PE), which adopts the form of distributor composite or in mold composite molds to precisely control the use of barrier materials, minimize the amount of use under continuous feeding, reduce costs, and also achieve no entry of high barrier materials within the cutting range.

Asymmetric structure multi-layer co extruded cast film (biopharmaceutical packaging film) production line: The characteristic of this type of equipment is that the cross-section of the produced product is multi-layer co extruded and asymmetric structure, requiring precise calculation and control of the amount and thickness accuracy of each layer of material, so that the final produced film is flat and invisibly shrink. This type of structured cast film is mainly used in the field of biopharmaceutical packaging.

PMMA Rainbow Film Production Line: Rainbow film, also known as Rainbow Film, Colorful Film, Phantom Film or Laser Rainbow Film, is a multi-layer plastic composite film. It is made of two or more resins with different refractive indices, extruded by melting and stacked layer by layer, with a total of over 200 layers. This structure allows the rainbow film to produce weak reflection and interference under light irradiation, thus exhibiting a colorful rainbow effect.

PP Decorative Film/PET Decorative Film Production Line: Decorative film is a new type of decorative material made from polymer as raw material, through multi-layer co extrusion, casting and pressing. It can be composite with substrates such as wood, plastic board, aluminum board, iron board, etc. to make multi-purpose decorative materials. The PET decorative film production line adopts a dual machine co extrusion form, which is usually used to manufacture "high gloss" or "skin feel" decorative films; The PP decorative film production line adopts a three machine co extrusion form, which is usually used to manufacture decorative films that can print various patterns.
