Different Types of Plastics
When selecting a plastic bottle or container, it is important to understand the different types of plastic and what each is best used for. Liquid Bottles offers a wide variety of sizes and shapes of plastic bottles and closures, all made from the plastics listed below that are considered food-safe by the FDA.
HDPE (High-Density Polyethylene): is the most widely used type of plastic bottles. This type of material is impact resistant, economical, and provides a good moisture barrier. This plastic is compatible with a range of products including acids, but is not compatible with solvents. HDPE can be translucent and flexible. When color is added it will make the HDPE opaque. The most popular color is white. Liquid Bottles offers packer bottles, 60ml bullet bottles, and gallon jugs in HDPE.
LDPE (Low-Density Polyethylene) is similar to HDPE. It is not as rigid and generally less chemically resistant than HDPE and is more translucent. This plastic is usually used mainly for squeeze applications. Liquid Bottles offers joint tubes, dripper bottles, and Chubby Gorilla in LDPE.
PET (Polyethylene Terephthalate) is used in many food products, water bottles, and soda bottles. PET has resin that is stable, which means that it will not degrade when it is in contact with food or beverages, it repels microorganisms, and resists corrosion. This is why it is why it is ideal for food contact. Liquid Bottles offers dripper bottles, packer bottles, and cosmo bottles in PET.
PP (Polypropylene)is used in many reusable containers due to its high melting point. It is also very stable and does not react to liquids, acids, or bases. Many of the caps offered by Liquid Bottles are made of PP, including our popular graduated and plain droppers.
