High barrier films are widely used in various industries and applications where protection against moisture, oxygen, light, and other external factors is critical. Some common uses include:
1. Food Packaging: High barrier films are extensively used in food packaging to extend shelf life, maintain product freshness, and prevent spoilage. They are used for packaging items such as meats, cheeses, snacks, coffee, frozen foods, and ready-to-eat meals.
2. Pharmaceutical Packaging: In the pharmaceutical industry, high barrier films are utilized for packaging medications, drugs, and medical devices to ensure their integrity and efficacy by protecting them from moisture, oxygen, and light.
3. Electronics: High barrier films are employed in electronics packaging to safeguard sensitive electronic components and devices from moisture, corrosion, and other environmental contaminants that can affect their performance and longevity.
4. Agricultural Products: These films are used in agriculture for packaging products such as seeds, fertilizers, pesticides, and mulches, providing protection against moisture, UV radiation, and other environmental factors.
5. Industrial Applications: High barrier films find applications in various industrial sectors for packaging chemicals, paints, coatings, adhesives, and other industrial products to maintain their quality and integrity during storage and transportation.
6. Medical Devices: They are utilized in packaging medical devices and equipment to ensure sterility and protection against contamination, moisture, and other external factors.
7. Cosmetics and Personal Care Products: High barrier films are used in packaging cosmetics, toiletries, and personal care products to preserve their freshness, aroma, and quality by preventing exposure to air, moisture, and light.
Overall, high barrier films play a crucial role in enhancing product quality, extending shelf life, and ensuring product integrity across a wide range of industries and applications.
Extruder
This is the heart of the extrusion line where the raw material, usually polypropylene resin pellets, is melted and homogenized. Extruder Its special extruding screw systems , precise manufacturing data , temperature controls and speed adjusting systems ensure stable good extruding ;
Dies
Dies Excellent Cr-plated heat resistant steel alloy is applied for T-dies , which flowing channels are of clothes-hanger type design , with excellent flow distributing systems , to make sure that flows can go evenly to all the whole dies ; A adjusting system equipped onto up and down die lips , to make sure that all sheets have good thicknesses ;It has a specific profile that determines the thickness and width of the film. The molten polymer is forced through the die head, forming a continuous sheet of film.
Cooling Unit:
After passing through the die head, the hot film needs to be cooled rapidly to solidify it. Cooling units typically use chilled air or water to cool the film to the desired temperature.
Haul-Off Unit:
Once the film is cooled and solidified, it needs to be wound onto a roll. The take-up unit consists of rollers that guide the film as it is wound onto a core to form a roll of finished film.
Thickness Gauge:
This is an optional component that measures the thickness of the film as it is being extruded. It provides feedback to the extrusion line control system, allowing for adjustments to be made to maintain consistent film thickness.
Corona Treater:
CPP film often requires surface treatment to improve adhesion for printing or coating processes. A corona treater applies a high-voltage electrical discharge to the surface of the film, which creates reactive species that enhance surface energy and promote adhesion.
Slitting Unit:
In some cases, the finished film may need to be slit into narrower widths. A slitting unit consists of blades or knives that cut the wide roll of film into multiple narrower rolls.
Winding Unit:
This unit winds the finished film onto cores or reels in a controlled manner. It ensures that the film is wound evenly and tightly to prevent wrinkles or damage.
Control System:
The entire extrusion line is typically controlled by a centralized control system. This system monitors and adjusts various parameters such as temperature, pressure, speed, and thickness to ensure optimal performance and product quality.
