Achieving a flawless seal with 89mm heat induction foil liners requires precision in material selection, equipment calibration, and process optimization. These universal liners are designed for compatibility with a wide range of container materials, including plastic (PET, PE, PP) and glass, making them ideal for industries like food, pharmaceuticals, and cosmetics. This guide outlines best practices to ensure optimal sealing performance while addressing common challenges.
An 89mm heat induction foil liner is a multi-layered component that creates a hermetic seal using electromagnetic induction. Key layers include:
- Aluminum Foil: Conducts heat to activate the polymer coating.
- Heat-Seal Polymer (e.g., LDPE, HDPE): Bonds to the container's lip.
- Backing Material: Foam or pulpboard for structural support.
- Optional Wax Layer: For two-piece liners, releases the foil during sealing.
- One-Piece Liners: Foam-backed for clean removal (ideal for dispensing closures).
- Two-Piece Liners: Include a wax layer; backing remains in the cap for resealing (e.g., Pres-On's 2PC-HISG for glass).
- Clean the Container Lip: Remove debris or residue using alcohol wipes.
- Insert the Liner: Ensure the foil side faces the container opening.
- Recommended Torque: 8–12 inch-pounds for most 89mm caps.
- Consequences of Improper Torque:
- Under-tightening: Weak seal.
- Over-tightening: Distorted container lip.
- Power Setting: Start at 30–40% power; adjust based on liner thickness (see Enercon's guidelines).
- Dwell Time: 1–2 seconds.
- Head Distance: Maintain 1/8 inch (3mm) between the sealer head and cap.
| Parameter | Recommendation |
|---|---|
| Power | 30–40% |
| Dwell Time | 1–2 seconds |
| Head Distance | 3mm (1/8 inch) |
- Vacuum Decay Test: Measures pressure changes to detect leaks.
- Dye Penetration Test: Identifies seal failures using colored dye.
Any tampering leaves visible foil residue on the container lip, complying with FDA and EU regulations.
The hermetic seal blocks liquids and gases, ideal for sauces, oils, and pharmaceuticals.
Blocks oxygen and moisture, preserving product freshness by up to 30% (as per GilPack's studies).
Universal liners seal to:
- Plastics: PET, PE, PP.
- Glass: Requires GlassFuze™-type polymer coatings (see Selig Group's solutions).
- Example: Hot sauces, dressings.
- Benefit: Prevents oxidation and maintains flavor.
- Example: Liquid medications.
- Benefit: Ensures sterility and tamper evidence.
- Example: Serums, creams.
- Benefit: Protects against evaporation and contamination.
- Reduced Waste: Hermetic seals minimize product spoilage.
- Bulk Purchasing: MOQs for 89mm liners start at 10,000 units (as per Technopack Corp.), lowering per-unit costs.
Achieving a perfect seal with 89mm heat induction foil liners hinges on precise liner selection, equipment calibration, and rigorous testing. By adhering to torque guidelines, optimizing sealer settings, and conducting integrity checks, manufacturers can ensure leak-proof, tamper-evident packaging. Universal liners' adaptability to glass and plastic containers makes them indispensable for industries prioritizing product safety and shelf life.
They seal to PET, PE, PP, and glass (with specialized coatings like GlassFuze™).
Use reinforced MYLAR pull tabs and ensure proper tab alignment.
Yes, but select high-temperature polymers (e.g., HDPE).
Typically 10,000–50,000 units (varies by supplier).
Use alcohol or adhesive remover; avoid abrasive tools to prevent container damage.
