Heat Seal
Liners for Plastic Caps
- Need
special equipment to apply liner: Heat Induction Machine
- Layers
of material
- Paper
or foam backing
- Foil
piece on top (bonded together)
- Liners
we stock are made to adhere to many different materials (PP and Styrene)
- Universal
seal (designed to stick to most materials but not welded)
- Need
special machine to apply to container
- Most effective way to prevent
leakage, but it’s not 100%
Pressure
Sensitive Liners for Plastic Tops
- Never
recommended for liquids
- Made
of polystyrene
- Designed
for use with dry products
- Like
a stronger post-it note
- Not
very sticky
- Designed for tamper evidence
- Very
brittle by design, when liner is tampered with creases form in liner to show tamper evidence
Foam Liners for Plastic Lids
- Good multipurpose liner
- Enhances
shelf life and sealing after it’s opened
- The
more you open and close the cap (over time), the less effective the liner becomes - Shelf life is very good though
- Good Moisture
barrier, but not leak proof
- May help in a lot of cases but it is not designed specifically to prevent leakage in transit
Cosmetic Disc Liners
- Mostly aesthetic
- Helps
keep barrier from outside, but not as effective as other liners
- Best
with dry products, creams, etc.
- Best use is to keep the product off of the lid and inside the jar where it belongs
- Best used with an unlined cap
