Disc Top Caps

Disc Top Lids

Disc top lids are made of two pieces: the skirt and the disc. To dispense product, you press on one side of the disc, causing the opposite to snap up. You can then reverse the process to store product. This closure is commonly used for dispensing shampoo, lotion, conditioners, creams, and other personal care products.

Made of polypropylene (PP), these lids have a high heat tolerance level and an excellent resistance to fatigue. Available in a variety of combinations of neck size, color and liner.

See our Liner Guide to find which liner best suits your packaging needs.

Type	Description	Benefits	Disadvantages	Best For
Foam Liner	A general-purpose liner, made of compressible polyethylene foam. These do not create a seal and are often used for leak prevention.	Compatible with metal, plastic, or glass containers Economical Can be used to take up room on the top of the cap when the thread of the neck is not high enough to achieve a tight closure	Fair to poor resistance against hydrocarbon solvents It is not advised to use these with paints, lighter fluid, adhesives, or polishes Does not create an airtight seal	General Purpose Household Water-based products
Pressure Sensitive Liner	A pressure-sensitive foam liner with one adhesive side that sticks to the container with the pressure used to stick on to the rim of the container. When the closure is removed, the pressure-sensitive liner remains on the top of the container. They are typically white on each side. These can come printed on one side with “Sealed for your protection” or can come unprinted.	Seal provides an extra level of protection that preserves the freshness of nonperishable dry products You do not need secondary equipment to make the seal, only regular torque application	Does not work well with liquids Recommended shelf life of 6 months For maximum storage life, store in a temperature range between 60 and 80 degrees, with relative humidity at 40-60%, and no direct exposure to sunlight These are not tamper-evident seals	Dry products Powders Thick liquids
Heat Induction Seal (HIS) Liner	They can be made with layers of pulpboard, wax, and foil. When the liner is heated, the wax melts to the container rim creating an airtight, hermetic seal. These can come printed with a message (such as sealed for your protection) or plain. These liners are applied to the container with the use of an induction sealing machine (see item 31917).	Provides tamper-evident seal Once the liner is removed, it cannot be reapplied to the container Creates an airtight, hermetic seal to help prevent leakage There are different types of induction liners (oils are non-compatible with certain liners) so additional testing is needed	Induction lined caps must be applied using an induction sealing machine The liner needs to be compatible with the resin of the container Not recommended for metal caps or glass There is variation within heat seal liners, so heat seal liners must be tested with the product and container	Pharmaceutical Food Liquid products
Polycone Liner	An LDPE cone liner that creates a wedge type seal across the top of the container providing a leak-proof seal for liquid products, virtually eliminating leakage, evaporation, and contamination.	Cone liners are stress crack resistant Form an exceptionally tight seal and offer a good chemical barrier	Not generally paired with plastic containers	Harsh Chemicals Liquids susceptible to evaporation Essential oils
