Packaging Closures Guide

Closures are a necessary component of packaging and shipping supplies. They are used to seal containers once they have been opened and also the ones that have not been opened. They serve several functions specific to their designs. The shape and size of closures vary according to the type of seal required. Products such as bottles, jars, sprays, and containers, all require firm sealing that ensures the content contained inside does not escape or leak out in the slightest.

Closures also effectively preserve the product content after initial opening, so to ensure it does not spoil. Some closures are also designed to serve as dispensing caps. With so many variations, you can easily find a suitable closure for any product.

Some Common Types of Closures

All closures have a common purpose, but some offer additional uses. Closures are also designed bearing in mind customer appeal, as a uniquely presented item leaves a satisfying experience for the customer. Depending on the content being packaged and the regulations that may apply to the product, you can opt for any of these common types of closures shared in the guide below:

- Child Resistant Package Closures: Complying with the Poison Prevention Packaging Act, these closures are designed to prevent easy opening for children under the age of 5. These are typically used by pharmaceutical companies. Many chemical products also include child resistant closures adhering to child safety standards.

- Continuous Thread Package Closures: Typically used in industries for food, pet and household, health and beauty products, continuous thread closures perform the basic function of pairing with containers that have spiral heads with a thread.

- Evident Package Closure: These closures give customers the assurance that the product is completely intact prior to purchase. These are commonly used for food, beverage, health and beauty items. Evident closures also provide protection against the counterfeiting of over-the-counter pharmaceutical products.

- Bar Top or T Top Package Closures: These closures are typically used for special foods. The bottom part of the closure is made of authentic or synthetic cork while the top part of the closure can be made of glass, plastic, wood or metal.

- Dispensing Package Closures: These closures are commonly used across food, household, health and beauty industries. They control the amount of content that is released during the time of use. These dispensing closures are well suited to products such as fertilizers, spices and other dry items. Additionally, they are best for dispensing liquid content. When it comes to sprayers and pumps, these two can serve as their own kind of dispensing closures.

Some Tips to Consider

It is crucial for you to select the right type of closure for the product that you are handling as part of the packaging process. Having in-depth information regarding your product and the conditions that are either favorable or damaging to it can save you from unpleasant outcomes. The right closure will help shape the outcome of the delivery service; hence carefully focusing on the following variations will prove worthwhile:

- Size and color (colors that complement the product)

- Personalized decoration for appeal (self-print, debossing etc)

- Lined and Unlined (study the liner specifications of the company)

For manufacturers the possibilities to factor in are endless, but it is worthwhile to test all their product closures for compatibility and efficiency. This will ensure all closures are designed to adequately meet the criteria that determines efficient performance.
