Caps and Closures in Packaging: Topping It Off Just Right

Liners, caps, and closures in packaging from Pipeline PackagingFrom threaded caps to lug caps to child-resistant caps to snap caps to induction-lined caps to brush caps, and various dispensing caps — flip-top spouts, pumps, sprayers, push/pull caps, droppers, and more — Pipeline Packaging has the most popular types of closures in stock.

Whether you need even distribution, complete stopping control, a tiny drop, or a full stream, Pipeline offers a wide array of closures that can do exactly what you need.

Our bottle closure guide provides a full overview of many types of closures, including specifications and common uses. Our sales and customer service team members are here to lend a hand, too.

Closure Product Profile: Child-Resistant Caps

These closures are required for certain types of products being packaged. A prime example is most over-the-counter drugs. A person must press down and then twist counterclockwise to open it. This makes it difficult for a child to open, while not making it difficult for adults to use. Child-resistant caps come in many different sizes and shapes.

Aligning You with the Right Liner

Pipeline Packaging offers a wide range of liner types, including 3-ply foam (F217), polyethylene foam, pressure sensitive (PS22), induction, polyvinyl, and Polyseal™ liners.

Whether you’re trying to prevent a leak, keep children from getting into your package, or anything in between, Pipeline offers all different sorts of liners for your packaging.

Our team knows just which liners will work best with the bottles, caps, and closures you decide to go with. Our cap liner guide provides details you need to know.

Closure Liner Profile: 3-Ply Foam (F217)

A 3-ply liner is a general-purpose liner, made of compressible polyethylene foam. These liners do not create a seal and are often used for leak prevention. F217 is a name brand and is often interchangeable with the foam liner. It is taste and odor resistant, has a low moisture-transmission rate, and is compatible with metal, glass, and plastic containers. Learn more about other liners on our website.

It’s What’s Inside That Counts

Whatever product you’re packaging — from household cleaners to food and liquor to cosmetics to pharmaceuticals to powders to alcohol to essential oils to acids and harsh chemicals, and more — you need the perfect closure or liner to protect it from supply chain elements and to protect people and their environments from your product.

Our team of experts is also well equipped to handle your questions related to regulatory guidelines that must be met, regardless of your industry. Chances are, we’ve been there and done that. Our lab will also conduct quality testing to ensure the closures and liners you select are right for the job you need them to accomplish, if necessary.

Go with the Distributor … Not the Manufacturer

When many of our customers looking for liners, caps, and closures in packaging first considered working with Pipeline Packaging, there was at least one question on their minds. Why work with a distributor and not a manufacturer?

Going directly to a manufacturer is a strategy that only a few, very large companies can accomplish and be satisfied. Why? Manufacturers deal only in high volumes with no alterations or deviations from what they normally produce. As an industrial distributor, Pipeline Packaging leverages its buying power so you can still receive competitive pricing.

Unlike manufacturers, we offer a great deal of flexibility through our core services, which allows you to modify stock packaging and palletizing, enjoy just-in-time (JIT) delivery, and consider value-added services like labeling, kitting, and customization without the volume constraints or rigidity of buying direct from the manufacturer.
