The versatility of super clear PVC film continues to find new applications in sectors ranging from agriculture to high-tech manufacturing, underscoring its enduring importance.

Detailed Manufacturing Process Flow of WANMAO Super Clear PVC Film

The production of high-quality WANMAO transpatrnt cover cloth super clear pvc sheet plastic film involves a meticulously controlled multi-stage process designed to ensure superior optical and mechanical properties. Our manufacturing adheres strictly to international standards, including ISO 9001 for quality management, ensuring consistency and reliability across all batches.

1. Material Selection and Preparation

• Resin Selection: We utilize high-grade PVC resin (Polyvinyl Chloride) specifically chosen for its inherent transparency and processability. Critical additives include plasticizers (e.g., DINP, DOTP, or TBC for phthalate-free options), stabilizers (e.g., calcium-zinc or tin-based for thermal stability), lubricants, and processing aids. These are carefully selected to meet target specifications for flexibility, cold crack resistance, and UV stability.
• Compounding: The raw PVC resin and additives are precisely measured and blended in high-speed mixers. This compounding process creates a homogeneous mixture, ensuring uniform properties throughout the final film. Temperature and mixing duration are critical parameters monitored to prevent degradation and achieve optimal dispersion.

2. Calendering Process

The calendering method is pivotal for producing high-quality super clear PVC films:

• Gelation: The compounded PVC mixture is fed into an extruder where it is heated and plasticized into a molten, viscous mass. This process ensures the complete melting and mixing of all components.
• Calendering Rolls: The molten PVC is then fed between a series of heated, counter-rotating precision-ground rolls (calenders). Through a carefully controlled sequence of nip gaps and roll speeds, the material is progressively flattened and thinned into a continuous sheet of the desired gauge. The surface finish of the rolls directly impacts the film's clarity and smoothness.
• Temperature Control: Precise temperature control across the rolls is paramount to achieve uniform thickness, optical clarity, and to prevent material degradation. Inconsistent temperatures can lead to defects such as streaking, waviness, or poor transparency.

3. Cooling and Annealing

• Cooling Section: After calendering, the hot PVC film passes through a series of cooling rolls, gradually reducing its temperature. Controlled cooling prevents warping, internal stresses, and helps set the film's dimensional stability.
• Annealing (Optional): For certain high-performance applications, an annealing step may be introduced to further relieve internal stresses and enhance dimensional stability, particularly important for films requiring exceptional flatness.

4. Surface Treatment and Winding

• Corona Treatment (Optional): For applications requiring enhanced printability or adhesion to other materials, corona treatment may be applied to the film surface. This process increases surface energy, improving wettability.
• Inspection: The film undergoes continuous online inspection using optical sensors and human oversight to detect any defects such as gels, fisheyes, inclusions, or variations in thickness and clarity.
• Slitting and Winding: The finished film is trimmed to the desired width and wound onto cores, typically in large rolls. Tension control during winding is critical to prevent wrinkles and ensure even roll formation.

5. Quality Control and Testing Standards

Throughout the entire process, rigorous quality control measures are implemented. Key tests performed include:

• Thickness Measurement: ANSI standards ensure precise gauge control.
• Tensile Strength & Elongation: ASTM D882 standards for mechanical integrity.
• Tear Resistance: ASTM D1922 standards.
• Light Transmittance & Haze: ASTM D1003 for optical clarity.
• Cold Crack Temperature: ASTM D1790 to determine low-temperature flexibility.
• Shore Hardness: ASTM D2240.
• Chemical Resistance: Internal protocols aligned with industry needs.
