Slip-On Caps are externally fitting closures specifically designed for packaging applications where it’s essential to take full advantage of the internal volume of a plastic tube. These caps are applied over the outer diameter of the tube, creating a secure seal without encroaching on the interior space. This makes slip-on caps particularly well-suited for precision applications where internal dimensions must remain consistent, such as in cosmetic, laboratory, or technical packaging. In addition, the simplicity of the slip-on mechanism allows for quick and easy manual or automated application, enhancing production efficiency.

In short, slip-on caps offer a unique combination of design and functional efficiency, making them a preferred choice when internal space is at a premium and clean, modern appearance is desired.

Vinyl

Vinyl

Vinyl caps are the most secure-fitting slip-on caps we offer, combining a snug hold with the flexibility needed to accommodate plastic packaging tubes of various sizes. Made from high-quality, pliable vinyl, these caps provide a unique combination of strength and adaptability—ensuring they stay firmly in place while remaining easy to apply and remove. The inherent flexibility of vinyl not only enhances durability and impact resistance but also creates a protective seal that helps safeguard contents from dust, moisture, and damage. In addition to their functional advantages, vinyl caps offer a smooth, glossy finish that enhances the visual appeal of your packaging, making them an excellent choice for both practical and aesthetic applications.

Polypropylene

Polypropylene slip-on caps are engineered using precision injection molding to deliver a durable, low-profile sealing solution that enhances both function and presentation. The choice of polypropylene offers excellent chemical resistance, impact durability, and dimensional stability, making these caps ideal for demanding packaging environments. The injection molding process ensures a high degree of consistency and allows for the integration of features like a lead-in chamfer on the bottom edge, which promotes easy alignment, smooth application, and effortless removal. These caps also have attractive knurled side finish for extra grip.

Butyrate

Butyrate

Butyrate slip-on caps are expertly crafted using a vacuum forming process which not only allows for precise, consistent shaping but also gives the cap its signature water-clear, glass-like appearance. The exceptional clarity achieved through this process makes these caps an ideal match for our clear plastic packaging tubes, resulting in a fully transparent package that allows the contents to be viewed clearly from any angle. This level of visibility enhances product presentation, making it particularly well-suited for retail applications where showcasing the item inside is essential. The seamless transparency of the butyrate cap and tube combination delivers both a professional appearance and functional clarity that sets it apart from opaque packaging solutions.
