Plastic Bottle Caps

A plastic bottle cap is the best way to close all kinds of containers, bottles, jerrycans and plastic packaging, and it protects the contents well. Every bottle, jerrycan and plastic container needs its own suitable cap. Any container used to store materials of any kind has always needed a closure, and in the past many different materials were used to cover the openings of containers. In 1892, William Painter invented the metal crown cap for glass bottles holding soft drinks and other beverages. These caps were so important that they are still used today and have become a key factor in protecting such containers. In the same way, buying the right plastic caps for your products preserves their shelf life. If you are looking to buy plastic bottle caps in bulk, read on for important tips that will help you make a better decision.

Types of Plastic Jerrycan and Bottle Caps

The plastic caps used to seal bottles and packaging come in many types. Here are the main ones:

Threaded (Screw) Plastic Caps

These include all the common plastic caps that open by twisting. They are made in many sizes, materials and colors, and with different numbers of threads; you can see examples among the products above. They are clearly the most widely used plastic bottle caps. They provide good liquid- and gas-tight sealing and can also have a tamper-evident band. Some of them are also made with a vent.

Measuring (Dosing) Caps

These caps are used mainly in industries whose products need to be measured out, such as detergents, including liquid laundry detergents and disinfectants. Sapel is one of the leading professional manufacturers of these plastic containers and parts, with deep expertise in the field. The price of a plastic dosing cap usually depends on the material it is made of. The image shows an example of this cap that Sapel makes for one of its customers.

Push-Pull Caps

Push-pull caps, some of which can also be opened and closed by twisting, are used in many industries, including food, chemicals such as adhesives, and personal care and cosmetics. When buying this type of plastic bottle cap, be sure to check its material and strength. The image shows an example of this cap made by Sapel.

Flip-Top Plastic Caps

The caps shown in the image are called flip-top caps. This type of plastic cap can be made in different shapes and sizes. As the image shows, it has a hinged lid on top that opens and closes easily, while the lower part screws on and off. Flip-top caps can also be made in other designs without the top lid. They are widely used for detergents and personal care products such as shampoo, dishwashing liquid and hand wash.

Spray Caps (Spray Top)

But these caps are not used only for disinfectants: they serve a wide range of products, including cosmetic and personal care solutions and protective sprays, and they are among the most widely used types of plastic bottle cap.

Trigger and Pump Caps

The image shows an example of each of these two types. Trigger caps are used for spraying, and you have surely seen them on surface cleaners. Pump caps dispense the product and can be designed for thick or thin liquids; liquid hand soap bottles are one place you may have seen them. Strong sales of trigger and pump caps show how popular they are: triggers are mostly used on cleaning and detergent sprays, while pumps dispense the product in thick or thin form.

Dropper Caps

This type of cap is widely used in industries such as pharmaceuticals and food. As the name suggests, it is used to dispense a product drop by drop. In some types, the liquid is drawn up and released through a plastic or glass tube by squeezing and releasing the top.
