As plastic squeeze tubes have evolved with many types and shapes available made from different materials, so have the tube necks and caps. Much like the squeeze tubes themselves, the different tube necks and cap styles now available provide dispensing capabilities unique for nearly any need in any industry.
The neck of the squeeze tube has two main functions. First, it’s the opening of the squeeze tube that allows the contained product to be dispensed. Second, it contains threads that hold the different types of caps, stoppers or closures onto the squeeze tube itself. One of the great squeeze tube innovations of recent years is the ability to create tubes with a choice of tube neck style and size along with a preferred type of cap or lid that is independent from the tube neck choice. This has created great diversity in the type of products that are put into squeeze tubes as well as easier use and less waste at the end user.
Generally, the thicker diameter of the tube neck and more threads that are on the neck, the more squeezable pressure the neck and tube can withstand. Having a thicker, more robust tube neck that withstands higher pressures allows you to package products that have a thicker viscosity. Some of these thicker viscous products include items such as caulk, adhesives and other types of heavy duty sealants. A thicker, longer tube neck also allows for more and bigger threads for a better seal and to secure the tube cap or lid if the tube is squeezed with the cap or lid on the tube.
When it comes to caps, there are now dozens of different options to choose from. This allows you to create a squeeze tube body and cap combination that is ideal for any single product you want to package and sell. Squeeze tube caps can be molded with custom colors to reflect and enhance your product branding. You can make your squeeze tubes stand out with foil or other metallic finishes that shimmer and reflect on caps as well.
