Product Description

Product Introduction

Overview

Our 8011 O temper aluminum foil rolls are engineered specifically for the precision manufacturing of bottle cap liners, induction seal liners, and heat-sealing packaging components. Known for its ultra-soft texture, excellent elongation, and pristine surface cleanliness, this material provides an absolute barrier against moisture, oxygen, gas, and light.

It is perfectly optimized as the core metallic barrier layer, readily accepting lamination or coating with PE, PET, PP, or PS films and wax backings. Whether you are producing tamper-evident induction seals for pharmaceutical bottles, cosmetic jars, or agrochemical containers, our factory-direct 8011-O foil ensures flawless bonding, zero leakage, and ultimate product freshness.

Key Product Advantages

Optimal Surface Wetting for Lamination

Processed through advanced degreasing and annealing techniques, our foil exhibits superb surface tension (high brush grade). This ensures that plastic films (PE/PET/PP) or heat-seal lacquers bond flawlessly to the foil without peeling or delamination.

Superior Thermal Stability & Heat Conductance

Perfectly suited for rapid high-frequency induction heating or direct thermal contact sealing lines, melting the polymer film uniformly for a hermetic seal.

High Purity & Cleanliness

Free from rolling oils, residues, or heavy odors, meeting the strict hygienic standards required by the pharmaceutical, food, and beverage packaging industries.

Excellent Punching & Slitting Yield

The uniform mechanical properties prevent tearing, edge deformation, or wrinkling during high-speed die-cutting and disk slitting.

Main Applications

Induction Foil Seals

Tamper-evident seals for HDPE/PET bottles in the pharmaceutical, nutraceutical, and cosmetic sectors.

Yogurt & Beverage Cup Lids

Laminated with plastic layers to create peelable or weldable lids for dairy, juice, and dessert cups.

Chemical & Oil Container Liners

Heavy-duty barrier liners providing maximum leakage protection and chemical resistance for lubricants or agrochemicals.

Factory-Direct B2B Advantages

Precise Gauge Control

Utilizing advanced automatic gauge control (AGC) rolling mills, we guarantee consistent finished thickness tolerances across the entire roll.

Sea-Worthy Export Packaging

Suspended wooden crate packing protects the delicate edges of aluminum foil rolls from compression, damage, or moisture ingress during ocean freight.

Global Supply Chain Reliability

We regularly export high-quality aluminum coils and foils with full traceability and Mill Test Certificates (MTC) according to international trade protocols.

Frequently Asked Questions

Q：Why is 8011-O aluminum foil ideal for induction sealing production?

A：The soft annealed O temper delivers great ductility and surface adhesion, while stable physical properties support high-speed lamination, coating and die-cutting. It also forms a tight barrier to stop gas and liquid leakage, fully matching the production demands of induction cap seals.

Q：Can you customize thickness and width for our production lines?

A：Yes. We support customized thickness and precision slitting based on your equipment and product design requirements to achieve perfect compatibility.

Q：Are your products compliant with international safety standards?

A：All our aluminum foil passes FDA, SGS, RoHS and REACH tests. Complete certification documents and mill test reports can be provided for every shipment.
