PE cast film equipment consists of an extrusion system, a cast film die, a cooling and shaping roller group, a traction and winding system, an electric control center, and a variety of optional online functional modules. The frame adopts a high-strength carbon steel welded structure, the surface is sprayed, and the core components are hard chrome plated or nitrided. This equipment is a high-precision and efficient polyethylene film production equipment, mainly used for the production of PE cast film.

1. High-performance screw system, uniform plasticization

The PE cast film equipment adopts a φ150mm screw or a φ150mm+φ90mm co-extrusion twin screw with an aspect ratio of 30:1, which has excellent melt uniformity and material dispersion. It is suitable for single-layer or multi-layer film co-extrusion production, with stable plasticization effect, avoiding the problem of uneven film thickness.

2. Wide die structure, flexible production

The width of the cast die is 2800mm and 3000mm, respectively, corresponding to the effective film width of 2300mm and 2400mm, respectively. Supports 1-3 layers of film structure design to meet the personalized needs of different terminal products for film structure.

3. Adjustable film weight, wide coverage

The PE cast film equipment can stably control the film weight between 14~60g/m² by adjusting the flow rate, traction speed and cooling temperature. It is suitable for a variety of application scenarios such as sanitary product base film and packaging film, saving materials while ensuring performance.

4. Efficient automatic winding system

The winding diameter can be selected as Φ600/800/1000mm, equipped with a center surface double-drive winding method, automatic film connection, support non-stop roll change, ensure production continuity, and increase production capacity by more than 20%.

5. High-speed operation, energy-saving and high-efficiency

The maximum line speed of the PE cast film equipment can reach 200 meters/minute. The use of efficient energy-saving drive system and heat recovery module reduces the comprehensive energy consumption by more than 15%, while ensuring the stability and uniformity of high-speed film formation.

6. Modular intelligent expansion capability

PE cast film equipment supports optional MES digital management system, online black gold tape pasting device, online thickness detection system, online edge material recovery device, online embossing slitting system, etc., to meet the needs of intelligent manufacturing upgrade.

1. Baby diaper production base

PE cast film equipment is widely used in the production of base film and wrapping film in overseas baby diaper factories, providing raw materials for the production of high softness and strong anti-permeability films. Cooperating brands include Huggies, Pampers, etc.

2. Adult incontinence care product manufacturer

PE cast film equipment can stably output ultra-thin PE film of 14~25g/m², which is used to manufacture the absorbent layer base film of adult diapers, ensuring the breathability and flexibility of the finished product, and has been adopted by brands such as Tening for a long time.

3. Pet urine pad factory

PE cast film equipment is widely used in the field of pet care products, especially the production of disposable pet urine pad base film. The film has a wide width and uniform thickness, which improves the absorption performance of the product. The long-term cooperative brand is Simple Solution.

4. Disposable mattress and medical protective equipment manufacturers

PE cast film equipment can produce medium-thick PE films of 20~45g/m² for the manufacture of disposable mattress films and waterproof layers for medical pads. Export markets cover the Middle East and South America, and partners include Medline Industries.

5. Food packaging manufacturers

PE cast film equipment is suitable for processing PE bottom films required for composite packaging. The film surface is flat and the tension is controllable. It supports post-printing and heat sealing. Currently, it has established cooperative relationships with packaging companies such as Sealed Air.

1. Clean the screw and barrel regularly

It is recommended to clean the barrel and screw every 500 hours of operation to remove polymer residues and prevent carbon deposition from affecting plasticization uniformity. Using PE cleaning materials or professional cleaning agents is more efficient.

2. Maintenance of the cooling roller water circulation system

Check the internal circulating water system of the cooling roller once a month to keep the water temperature stable, and replace the filter element and softened water to prevent scale clogging from affecting the cooling rate and transparency of the film.

3. Inspection and calibration of online thickness measurement system

The online thickness measurement system should be calibrated once a quarter to ensure that the uniformity of film weight meets the customer acceptance standards.

4. Adjustment of tension control of winding system

According to the change of film roll diameter, timely calibrate the tension control parameters to prevent wrinkles on the edge or film surface, especially in high-speed operation.

5. Lubrication and electrical contact point inspection

Check the lubrication of the chain, bearings and slide rails every two weeks, and use special high-temperature grease; at the same time, confirm that the joints of the electrical control box are tight and free of oxidation to ensure long-term stable operation.
