Durable Plastic Curtain Strips: Cold Room & Cooler Solutions

The Advanced Manufacturing Process of High-Quality PVC Strip Curtains

The production of our High-Quality Transparent PVC Strip Curtain involves a meticulously controlled manufacturing process to ensure superior performance, clarity, and durability. Our commitment to excellence begins with the selection of premium raw materials and extends through every stage of production, culminating in a product that meets rigorous international standards. This stringent process ensures that our products, whether for petrochemical plants or food processing facilities, deliver consistent quality and a long service life.

Detailed Process Flow:

Material Selection & Compounding

We utilize virgin suspension-grade PVC resin, carefully compounded with specialized plasticizers, heat stabilizers, UV inhibitors, and other performance additives. This proprietary formulation is critical for achieving optimal flexibility, clarity, UV resistance, and cold crack properties, especially for applications like fridge curtains. This initial step involves precise measurement and mixing to create a homogeneous compound ready for extrusion, adhering to ISO standards for material composition.

Extrusion Process (Casting)

The compounded PVC material is fed into a high-precision extruder. Through a process analogous to casting, the material is melted under controlled temperature and pressure, then forced through a die to form continuous strips of the desired width and thickness. Our advanced extrusion lines ensure uniform dimensions and consistent material density, crucial for the long-term integrity of the plastic curtain strips in demanding industrial environments.

Cooling and Shaping

Immediately after extrusion, the hot PVC strips pass through a series of cooling rollers. This controlled cooling process solidifies the material and helps maintain dimensional stability. For ribbed strips, specialized rollers apply the characteristic ribbing pattern, enhancing durability and minimizing surface contact wear, making them ideal for heavy-duty plastic curtain door strips in high-traffic settings.

Cutting and Finishing

Once cooled, the continuous strips are precisely cut to specified lengths using automated cutting machinery. Edges are often rounded or chamfered to prevent sharp corners, improving safety and ease of installation. This precision ensures uniform product quality across large orders and compliance with dimensional tolerances outlined in ANSI standards.

Quality Control & Testing

Every batch undergoes rigorous quality assurance testing. This includes:

Dimensional Accuracy: Verification of width, thickness, and length against specifications.
Clarity & Transparency: Optical inspection for defects, bubbles, or discoloration.
Hardness (Durometer A): Adherence to specified Shore A hardness (e.g., 75-85) per ASTM D2240.
Tensile Strength & Elongation: Evaluation of mechanical properties per ASTM D412.
Cold Crack Resistance: Testing flexibility at low temperatures to ensure suitability for cold room curtains environments.
UV Stability: Accelerated weathering tests to confirm long-term outdoor performance.

These tests ensure compliance with international standards such as ISO 9001 for quality management systems and relevant ANSI standards for material properties, demonstrating our expertise and authoritativeness.

Packaging & Dispatch

Finished plastic curtain strips are carefully rolled and packaged to prevent damage during transit. Each roll is clearly labeled with product specifications and batch information, ready for dispatch to target industries including petrochemical, metallurgy, food processing, and water supply & drainage, where energy saving and corrosion resistance are key advantages.

Real-World Application Case Studies

Our commitment to quality and performance is best demonstrated through the successful implementation of our plastic curtain strips in challenging industrial environments. Here are a couple of examples illustrating their tangible impact on operational efficiency and cost savings.

Case Study 1: Large-Scale Food Distribution Center

Client: Major National Food Distribution Company (Operations in North America)

Challenge: The client operated a vast cold storage facility requiring frequent forklift access, leading to significant temperature fluctuations and energy loss at freezer and cooler doorways. Existing fabric strip curtains were prone to damage, offered inadequate thermal insulation, and required frequent replacement, resulting in high refrigeration costs and substantial maintenance. Ambient temperatures would often penetrate the cold zones, causing product degradation and increased energy load.

Solution: We conducted a thorough site assessment and recommended the installation of heavy-duty, low-temperature plastic curtain strips (400mm width, 4mm thickness) with a ribbed profile at all high-traffic cold room entrances. These cooler strip curtains were designed with an optimal 75% overlap to maximize thermal efficiency while allowing smooth passage for forklifts and personnel. We also provided stainless steel mounting hardware for corrosion resistance in the moist cold environment.

Results: Post-installation, the client reported a measurable 45% reduction in refrigeration energy consumption within the first six months, leading to an estimated annual saving of $35,000 for that facility. The durable ribbed strips withstood heavy forklift traffic without significant damage, drastically reducing maintenance and replacement costs by 70%. The improved thermal barrier maintained more stable internal temperatures (variance reduced by 8°C), enhancing product quality and significantly reducing spoilage risk. Customer feedback highlighted improved visibility and safety for forklift operators due to the sustained clarity of the strips, along with a noticeable reduction in frost buildup. This project demonstrated a clear return on investment within 1.5 years.

Case Study 2: Chemical Processing Plant

Client: Regional Chemical Manufacturing Facility (Southeast Asia)

Challenge: The plant needed to create segregation between a corrosive chemical mixing area and an adjacent packaging zone. The mixing area generated acid and alkali fumes, and airborne dust was a constant concern for product purity in the packaging area. Previous attempts with non-specialized barriers resulted in rapid material degradation and inadequate containment, posing both safety and quality risks.

Solution: Based on a detailed analysis of the chemical exposure and operational traffic, we recommended and installed chemically resistant, clear plastic curtain strips (300mm width, 3mm thickness) at the interface. The specific PVC formulation was chosen for its enhanced resistance to the prevalent acids (e.g., HCl, H2SO4) and alkalis in the mixing area, as validated by internal lab tests and industry benchmarks. The strips were installed with a high overlap to maximize barrier effectiveness against fumes and particulates.

Results: The installation successfully created an effective barrier, significantly reducing the migration of corrosive fumes and airborne dust into the packaging area, thereby improving product quality and worker safety. Air quality monitoring in the packaging zone showed a 60% reduction in particulate matter and a 75% reduction in detectable chemical vapors. The transparency of the strips maintained critical visual oversight between the two zones, facilitating coordination and safety. The chemical-resistant properties of the PVC ensured a prolonged service life (estimated 6 years+) compared to previous solutions, with no signs of degradation or embrittlement after two years of continuous exposure. This demonstrated the material's superior corrosion resistance and longevity in an extremely challenging environment.
