(4) Environmentally friendly packaging

Single-material PET composite packaging (recyclable alternative to traditional multi-layer composite materials).

4. Comparison with competing materials (PET vs. PE/PP/PVC)

Material	Transparency	Strength	Heat Resistance	Barrier Properties	Eco-Friendliness	Cost
PET	★★★★★	★★★★	★★★★	★★★★	★★★★★	Medium-High
PE	★★	★★	★★	★★	★★★	Low
PP	★★★	★★★	★★★	★★	★★★	Low
PVC	★★★★	★★★	★★	★★★	★	Medium

PET Core Advantage: Achieves the best balance between transparency and strength while meeting environmental requirements.

How to produce high quality PET plastic rolls?

Producing high quality PET plastic rolls involves several steps, and attention to detail at each stage is crucial. Here’s an outline of the key factors involved in ensuring high quality:

1. Raw Material Selection

• High Grade PET Resin: The quality of the raw material is fundamental. Ensure that you use high-grade PET resin, preferably from trusted suppliers, to avoid impurities or low molecular weight which can affect the strength and clarity of the final product.
• Additives: Use additives like stabilizers, UV inhibitors, and plasticizers, if needed, depending on the intended use of the PET rolls (e.g., for food packaging or electronics).

2. Polymerization Process

• Polymerization Quality Control: PET resin is produced through polymerization, and this process needs strict quality control to ensure uniform molecular weight distribution. Proper control of temperature and reaction time ensures high-quality PET.
• Viscosity Control: Viscosity plays a huge role in the final quality of PET films. Maintaining the correct viscosity ensures smooth production without defects.

3. Extrusion Process

• Extrusion Temperature: The extrusion temperature should be carefully controlled to avoid degradation of the polymer. Typically, a temperature range of 250°C to 280°C is used for extrusion.
• Extruder Quality: Use high-quality, well-maintained extruders to ensure uniform thickness and quality. Also, ensure that the screws and barrels are suitable for PET processing.

6. Quality Control and Testing

• Mechanical Properties: Conduct tensile strength, elongation, and impact resistance tests to verify the durability and performance of the PET plastic rolls.
• Surface Defects: Inspect the surface for any scratches, bubbles, or unevenness. These defects can impact the usability of the final product, especially in industries like packaging or electronics.
• Thermal Stability: Ensure the PET plastic rolls maintain stability at higher temperatures, especially if they are intended for food or beverage packaging.

7. Slitting and Winding

• Precision Slitting: When the large rolls are slit into narrower widths, precision is crucial to prevent jagged edges or uneven tension.
• Winding Tension: The winding tension of the final roll should be adjusted properly to avoid issues like overstretching, tearing, or rolling defects.

8. Packaging and Storage

• Packaging: Pack the PET rolls carefully to avoid damage during transportation. Use protective layers to prevent scratches or pressure marks on the surface.
• Storage Conditions: Store the rolls in a clean, dry area, away from direct sunlight or sources of heat to maintain their quality over time.

9. Customization and Coating (if needed)

• Special Coatings: In some cases, you may need to apply coatings (e.g., anti-fog or anti-static) or further customization to suit specific customer needs.
• Surface Treatment: Treatments like corona discharge can improve the surface adhesion properties, especially for printing or coating purposes.

By managing each step with precision, from raw material selection to final packaging, you can ensure that your PET plastic rolls are of the highest quality, free from defects, and suitable for a wide range of applications.

How to Choose High-Quality PET Plastic Sheets? — A Professional Guide for Packaging Buyers

When selecting high-quality PET plastic sheets, packaging buyers can refer to the following professional guidelines:

1. Material and Performance

Ensure that the PET plastic sheets are made from high-quality raw materials, offering excellent transparency, toughness, heat resistance, and chemical resistance. Make sure it meets specific packaging requirements, such as compliance with food contact material standards for food packaging.

2. Thickness and Size

Choose the appropriate thickness and size based on packaging requirements. The thickness of PET plastic sheets generally determines its strength and transparency. Consider the product’s protection needs when making a selection.

3. Surface Treatment

Understand the surface treatment technologies of the PET sheets, such as embossing and coating, to ensure it is suitable for the required printing and packaging processes, enhancing the packaging’s appearance and functionality.

4. Environmental Friendliness

Choose PET plastic sheets that meet environmental standards, ensuring they are recyclable, non-toxic, and meet industry-specific environmental guidelines.

5. Supplier Reputation and Certification

Select suppliers with a good reputation and relevant certifications to ensure product quality and service. ISO certifications, food-grade certifications, etc., are guarantees of quality.

6. Price and Supply Capability

Consider both price and the supplier’s ability to provide consistent and stable supply. Choose suppliers who offer reasonable pricing and can maintain long-term, stable supply to avoid production disruptions due to shortages or price fluctuations.
