Plastic Closures: Lids, Caps and More

Plastic closures are an important part of many packaging solutions. They keep the product sealed and can be used to dispense the product as well. There are many different types of closures, and each one has its own benefits and drawbacks. In this blog post, we will discuss the different types of plastic lids and what makes them unique. We will also talk about how to choose the right plastic closure for your product!

What are plastic closures and what are they used for?

Plastic closures are used to seal products and prevent them from leaking. They can also be used to dispense the product, such as shampoo or conditioner. There are many different types of plastic lids, including screw caps, snap top lids, disc tops and more.

The different types of plastic lids

Non-Dispensing Continuous Thread Plastic Caps

  • Child-Resistant Caps - These caps are designed to be difficult for children to open. Child-resistant caps often have a higher thread count and require two hands to open.

  • Phenolic Caps - These caps are made of a heat-resistant material. They are often used for products that need to be sterilized, such as medical devices.

  • Dome Lids - These plastic lids are raised in the center and have a concave bottom. They are often used for products that are thick or viscous, such as lotions or creams.

  • Smooth Lids - These lids are smooth on the top and sides and typically made from PP (polypropylene).

  • Ribbed Lids - Ribbed lids are ribbed around the skirt of the lids to make opening and closing easier. The top can be smooth or matte.

Dispensing Lids

  • Snap-Top Caps - These plastic caps are easy to open and close. They are often used for products that need to be accessed frequently, such as mouthwash or lotion

  • Disc Top Caps - These plastic caps have a disc on the top that can be pushed down to open. They are often used for products that are thick or viscous, such as shampoo or conditioner.

  • Turret-Style Spout Caps - These plastic caps have a spout that can be used to dispense the product. Spout caps are often used for products that are thin or watery, such as cleaners or solvents.

  • Yorker Caps - These plastic caps have a long spout that can be used to dispense the product. They are often used for products that are thick or viscous, such as paint or glue.

  • Push-Pull Caps - These plastic caps have a tab that can be pulled to open the spout. They are often used for products that are thin or watery, such as juices or syrups.

  • Twist Open/Close - These plastic caps can be twisted open and closed. They are often used for products that need to be accessed frequently, such as adhesives or condiments.

How to select the right type of closure for your product

Knowing which closure to use for your product is essential. If you are packaging a viscous product such as lotion or shampoo then a disc top or snap top might be the right cap for you. If you are needing a lid for your jar of body butter then a smooth, ribbed or dome continuous thread lid would be great. If you're not quite sure which cap is best for you, then a good way to find out is to find a product similar to yours and use what they're using. It's perfectly okay to copy.

The benefits of using plastic lids

Plastic closures are an excellent way to seal and protect your product. They can also be used to dispense your product, which makes them very versatile. They are also very affordable and come in a variety of shapes, sizes and colors. Plastic is a great option because it's durable. When you open your shampoo bottle hundreds of times, you don't want your lid breaking.

Closure decoration and branding options

When it comes to decorating plastic lids you have a couple of options. You can either have a logo or design printed on the top of the lid, or you can have your design printed on a label that will adhere to the top of the lid.
