Plastic caps are found on everything from soda bottles to shipping containers. Manufacturers produce them in a near endless array of sizes, shapes and colors, from a wide range of plastics. Like most common plastic products, plastic caps offer a number of advantages, including cost-effectiveness, durability, customizability and chemical stability. In the many applications suited to plastic caps, these advantages amount to exceptional financial savings and commercial dependability.

For example, plastic caps provide the ideal economic solution to food and beverage storage. Properly applied caps can vacuum seal a container and supply consumers with an easy storage solution. They also make the package nearly tamper-proof. Produced in mass quantities, the cost of these caps to manufacturers is negligible. With a standardized set of bottles or other packaging, a single cap design can provide a top to an entire line of products. Soda bottles are an ideal example of this concept, and any look at a soda company’s product line will illustrate the flexibility of a single cap design.

Plastic caps are not only used in the food and beverage industry, however. Furniture design, chemical storage, medical supplies and electronic supplies all use forms of plastic caps. Even a camera lens cap is a specialized shape and design of plastic cap. Medicine bottles feature another specialized design that offers both child-safety and storage benefits. Spice and salt containers feature another type of specialized cap—a sifter—that allows users to generate a specific flow from the container.

The art and cosmetics industries also rely on plastic caps to package a wide assortment of products. Plastic glue caps can feature an attached brush or a closeable seal, while makeup (from lipstick to eyeliner) is packaged with many varieties of custom and standard caps. Paint bottles, pens and ink containers all utilize different sizes and shapes of plastic caps. Each industry demands different designs and qualities, and there are a surprising number of manufacturers able to meet the needs of these industries.
