Introduction of PET plastic sheet rolls for disposable drink cup

PET plastic sheet rolls for disposable drink cups are lightweight, transparent, and have excellent barrier properties, making them ideal for food packaging. They're commonly used in the production of clear drink cups due to their durability and safety for food contact.

Product Description

PET (Polyethylene Terephthalate) plastic sheet rolls are widely used in the production of disposable drink cups due to their favorable properties. These rolls are made from a thermoplastic polymer that is both lightweight and robust, ensuring that the cups can withstand temperature variations and maintain structural integrity.

Product Applications

1. Disposable Cups: Commonly used for serving cold drinks, such as sodas, juices, and iced coffees.

2. Food Service: Ideal for fast food and catering services due to their convenience and disposability.

What is the use of disposable plastic drink cups?

Disposable plastic drink cups are designed for single-use and are typically made from materials like polyethylene (PET). Their main functions include:

1. Convenience: They can be discarded after use, eliminating the need for washing and saving time.

2. Hygiene: Each cup is a new product, reducing the risk of cross-contamination.

3. Lightweight and Portable: They are suitable for various occasions, such as parties, picnics, and fast-food restaurants.

4. Variety: They can be produced in different shapes and sizes to meet diverse beverage needs.

5. Cost-Effectiveness: They are relatively low-cost to produce, making them suitable for large-scale use.

In summary, disposable plastic drink cups play an important role in providing convenience and hygiene.

What is PET plastic sheet rolls？

PET plastic sheet rolls are a continuous roll of polyethylene terephthalate (PET) plastic film, widely used for various applications. It is known for its excellent clarity, strength, and chemical resistance. Key features include:

1. Transparency: PET plastic sheet rolls are highly transparent, making them ideal for packaging and display purposes.

2. Durability: They offer good impact resistance and are less prone to breakage compared to other materials.

3. Barrier Properties: PET plastic sheet rolls provides effective barriers against moisture and gases, helping to preserve the freshness of packaged products.

4. Versatility: They can be easily customized in terms of thickness, size, and finish, suitable for a range of applications, from food packaging to industrial uses.

5. Recyclability: PET plastic sheet rolls are one of the most widely recycled plastics, supporting environmental sustainability efforts.

Overall, PET plastic sheet rolls are a popular choice in industries like packaging, food service, and manufacturing due to their performance and versatility.

How to produce PET plastic sheet rolls for disposable drink cup?

To produce PET plastic sheet rolls for disposable drink cups, the following steps are typically involved:

1. Raw Material Preparation

PET Resin Selection: Begin by selecting high-quality PET (Polyethylene Terephthalate) resin. This resin is typically in pellet or granule form, and for drink cups, food-grade PET (FDA approved) is necessary.

Drying Process: PET resin absorbs moisture, which can negatively affect the material's properties. The resin is dried in a dehumidifying dryer to reduce the moisture content, typically below 0.005%.

2. Extrusion Process

Extruder Feeding: The dried PET resin is fed into an extruder. Inside the extruder, the resin is melted by high temperature and mechanical shear.

Screw Design: The extruder screw design ensures consistent melting, mixing, and homogenizing of the resin. The temperature is carefully controlled, usually between 250°C and 290°C, to maintain material integrity.

Additives: Additives like colorants, UV stabilizers, or anti-block agents may be mixed into the resin if required for specific properties like transparency or UV resistance.

3. Sheet Formation

Sheet Die: The molten PET is forced through a sheet die, which forms a flat, thin, and continuous sheet. The width and thickness of the sheet are controlled at this stage. For drink cup applications, common thicknesses range from 0.2mm to 0.8mm.

Calendering: The extruded sheet passes through calender rolls, which cool and further control the thickness. The rolls are usually water-cooled to ensure the sheet solidifies evenly without warping.

Surface Finishing: The calendering process also imparts surface finishes like gloss or matte, depending on the requirements.

4. Cooling and Trimming

Cooling: After calendering, the PET plastic sheets are cooled down on a cooling conveyor or in water baths to stabilize its dimensions and prevent shrinkage.

Trimming: The edges of the sheet are trimmed to the desired width to ensure consistency. The trimmed material is often recycled back into the production process.

5. Winding

Rewinding into Rolls: Once cooled and trimmed, the PET plastic sheets are wound into large rolls for easy handling and transportation. The winding tension must be carefully controlled to avoid wrinkles or creases in the sheet.

6. Quality Control

Inspection: The PET plastic sheet rolls are inspected for defects like thickness uniformity, clarity, and surface finish. They also undergo mechanical tests to ensure they meet the required properties for thermoforming into disposable drink cups.

7. Thermoforming (Optional)

In some facilities, the PET plastic sheet rolls may directly proceed to thermoforming, where the rolls are heated and molded into the final shape of drink cups using molds.

The resulting PET plastic sheet rolls can then be sent to manufacturers that will use thermoforming machines to create disposable drink cups for various applications.
