An integral part of having successful packaging is the closure solution you choose. Packaging closures perform several functions but are primarily used to seal packaging and protect the contents inside. 

With the many different types of packaging closures available, it can be difficult for businesses to decide which one is best for their products. Regardless of the types of products your company sells, you can benefit from using quality packaging closures to protect your products.

Key Takeaways

  • When choosing the ideal closure for your packaging, you need to consider which closure system will provide the best protection for your products and the most ease-of-use for your target market.
  • There are two major categories of packaging closures. These are dispensing closures and non-dispensing closures.
  • Non-dispensing closures merely seal and protect the product inside, whereas dispensing closures provide a simplistic method of getting your products out of the packaging.
  • There are also other types of closures that serve specific purposes, such as preventing children from accessing the contents of the packaging. Flexible packaging can utilize specialized types of closures that are not compatible with rigid packaging.
  • Plastic Packaging Technologies is a leading manufacturer of flexible packaging solutions. We offer several different packaging options that can be customized with a number of enhancements and closures. Take a look at our products!

Benefits of Choosing the Right Packaging Closure

Because there are so many different types of packaging closures, it can be a lot for a business owner to digest. However, one thing is for sure: there are many benefits to choosing a quality packaging closure. 

Protect Product Quality

The primary objective of packaging is to preserve the product inside. Packaging closures play a critical role in protecting the product. Packaging closures act as an oxygen barrier to preserve product freshness, taste, and nutritional value.

The airtight vacuum seal emits an audible pop during the initial opening, guaranteeing that the product has not been tampered with. It assures customers that they can enjoy a fresh and safe product.


Product packaging has to be easy for the customer. If customers are not able to open the product easily, they are less likely to appreciate the product as much as they normally would. 


It could potentially turn them on to another brand out of frustration. Luckily, with innovations in packaging closures, products are becoming substantially easier to open.

Brand Differentiation & Engagement

Most product packaging features photos and messages, but packaging closures provide unique real estate that companies can use to further solidify their branding.

The central packaging closure panel is an ideal location for brand logos. High-quality, realistic images can be printed around the closure to capture customer attention. 

Business owners should take advantage of various decorative opportunities to differentiate their product from their competitors’. For example, a special message or company tagline could be revealed every time someone opens your product.

Flexible Packaging Closures

There are several types of packaging closures designed specifically for flexible packaging. These include the following.

  • Press-to-close zippers
  • Hook-to-hook closures
  • Slider closures with end clips
  • Inno-lok zippers
  • Spouts and fitments
  • Laser scoring, tear notches, and micro-perforations

Press-to-Close Zippers

Press-to-close zippers streamline the process of opening and closing a package. This is perfect for products that need to be kept sealed in their packaging to maintain freshness. That way people don’t have to rely on clips to keep the package closed.

Hook-to-Hook Closures

Hook-to-hook closures function similarly to press-to-close zippers in that they allow consumers to easily open and close packaging for further use. VELCRO Brand PRESS-LOK closures are known for their distinctive sound when opening/closing.

Slider Closures with End Clips

This advanced slider technology enables simplified opening and closing of bags and other similar flexible packaging. They are perfect for large bag applications, such as dog food or mulch for your yard.

Spouts and Fitments

These dispensing closures designed specifically for flexible packaging allow for an easy way to get liquid products out of their packaging. They are perfect for kids’ snacks, such as applesauce and other convenient on-the-go food items.

Laser Scoring, Tear Notches & Micro Perforations

These three methods of sealing flexible packaging allow consumers to easily tear off the top of the package. They are perfect for single-use applications and aromatic marketing.

Dispensing Closures and Non-Dispensing Closures

There are two categories of packaging closures: dispensing closures and non-dispensing closures.

Category I: Dispensing Closures

Common types of dispensing closures include the following.

  • Disc-top caps
  • Fine mist sprayers
  • Glass droppers

Tamper Evident Closures

Tamper evident closures are used to provide confirmation to the consumer that the original product is intact. They also have anti-counterfeiting security for over-the-counter (OTC) pharmaceuticals and nutraceuticals. Tamper evident closures are very popular in the frozen food, beverage, health, and beauty industries.
