We specialise in creating custom plastic packaging using a method called thermoforming. But what exactly is thermoforming, and why is it a smart choice for packaging your products in Singapore?
What is Thermoforming?
Thermoforming is a manufacturing process where a plastic sheet is heated until pliable, then shaped over a mould to create a specific form. It will be cooled down and trimmed and the newly formed part will be ready for use. This process is ideal for producing lightweight, durable packaging trays and enclosures at high volumes.
Thermoforming is used in manufacturing packaging for agricultural products, pharmaceutical products, consumer goods, domestic appliances, and more. It is also used in manufacturing durable end-use parts such as aircraft components, material handling equipment, automobile interiors, and medical equipment.
Compared to other conventional manufacturing processes, thermoforming enables manufacturers to produce small to large volumes of packaging at an affordable cost. The ability to utilize almost all thermoplastic types to rapidly produce high-quality end-use items is another important advantage of thermoforming.
Thermoforming Process – Step by Step
At Megapac, we specialise in vacuum forming and pressure forming.
Vacuum Forming: a thermoforming process where a thermoplastic sheet is heated to a pliable state, using controlled temperature, then pulled against a three-dimensional mould, by vacuuming out air between the plastic sheet and the mould.
Pressure Forming: a thermoforming process where a thermoplastic sheet is heated to a pliable state, using controlled temperature, then pressed against a three-dimensional mould by simultaneously vacuuming out air between the plastic sheet and the mould and applying air pressure above the plastic.
Thermoforming Materials
- Polypropylene (PP): PP is the most popular plastic material for thermoforming in terms of value and volume. It is commonly used in manufacturing packages, ventilators, toys, and other plastic items. Polypropylene is used because of its innate properties such as excellent resistance to chemicals, fatigue, and heat. Polypropylene is also an affordable material and can be used with the diverse thermoforming processes highlighted here.
- Polystyrene (PS): This aromatic hydrocarbon polymer provides manufacturers with a clear, hard, and brittle plastic to work with. Polystyrene is widely used as a thermoforming packing material as it offers qualities such as resistance to water and air. Manufacturers use polystyrene to manufacture food packaging, jewel cases, CD cases, and domestic items.
- Polyethylene Terephthalate (PET): PET provides very good alcohol and essential oil barrier properties, good chemical resistance, and a high degree of impact resistance and tensile strength. It is commonly used for carbonated beverages, water bottles, and many food products.
- Amorphous Polyethylene Terephthalate (APET): This is the amorphous or non-crystalline form of PET. It’s produced by controlling the cooling process during manufacturing to prevent crystallisation. This results in a transparent and glossy material, making it suitable for applications where product visibility is important, such as clear packaging and blister packs.
- Polyethylene Terephthalate Glycol (PETG): A modified PET that includes glycol in its chemical structure, enhancing its flexibility, impact resistance, and chemical resistance
Benefits of Thermoforming in Packaging
