Choosing The Right Closure

Once you have chosen your bottle or container you wish to use with your product the next step is to choose the right closure. There are several things to consider such as color, style, and function. Color and style may be just a choice of personal preference or they can serve as a distinguishing characteristic or marketing tool. For example you may want to have different colors of lids if you have a line of products with similar containers and labeling making it easy for your customers to quickly identify what they are looking for. The color and style of your closure can help your product stand out and get noticed.

A closures function goes beyond simply keeping your product in its container; it plays a role in how your customers use your product. Dispensing closures make it easier for your customer to get the right amount of your product, sprayers and pumps make it easier to use or apply your product. Child resistant closures can help keep your product secure and keep children safe. We can help you find the right closures and applicators that you deliver the best experience to your customers.

Choosing a Liner

The most important aspects of closures, especially in the food industry, are to help maintain freshness and provide a tamper evident seal. There are several different kinds of liners that provide different functions. Some products can react to different kinds of liners, some products work better with one liner over another. It is important to find out, and in some cases test, which liner works best with your chosen container and with your product.

Pressure Sensitive Liners

Pressure sensitive liners adhere to the top of a bottle or container when screwed down tightly. These liners tend to work best with powdered and dry products. The glue used to seal the liner to the bottle or container tends to not work as well if it gets wet from fluid or oil. Once the liner is removed from the bottle or container there is typically no liner in the cap to reseal your product, some caps may have a pressure sensitive liner as well as a secondary foam liner but this is not common. Pressure sensitive liners tend to work only as a tamper evident method of sealing your product.

Foam Liners

Foam liners are liners that stay in the closure. The benefit of foam liners is that they can help reseal your product each time the cap or closure is put back on the bottle or container. These liners work well with liquids and other products that could leak or spill. Closures with foam liners do not always come with a tamper evident option.

Heat Induction Liners (Foil Liners)

Heat induction liners or foil liners provide the best tamper evident and freshness seal for both wet and dry products. Foil liners are made to work with the specific type of plastic your bottle or container is made from, however there are also universal foil liners that work with all kinds of plastic bottles. Like the pressure sensitive liners these adhere to the top of the container and must be removed by the consumer providing a clearly tamper evident seal. Heat induction liners require a machine to adhere the liner to the container.

Vented Liners

Some products may give off gas or expand and require a vent in the liner to maintain the packaging shape and integrity. There are foil liners that will allow this to happen while still providing a tamper evident and freshness seal.

Tamper Evident Closures

There are several options available to provide a tamper evident closure for your product. Pressure sensitive and foil liners adhere to a containers opening and must be removed by the consumer. Pails and tub closures can have a tab that must be removed to remove the lid. We also carry several sizes of shrink bands that can fit on both bottles, jars, and plastic tubs.
