Pharamceutical Strip Packaging Foil

Specifications

material structure

The basic material structure of aluminum foil can be divided into two categories:

Al + LDPE (no printing)

OP + printing + Al + LDPE

Al and LDPE are connected by adhesive.

Thickness

AL: 25 – 50 micron

PE: 30 micron, 35 micron

Adhesive: 4.5 – 5 micron

Packaging and Storage

Proper packaging and storage are essential to maintain the quality of aluminium strip foil. Here are the recommended practices:

Packaging

Inner Packaging: Rolls are wrapped in polyethylene film to prevent moisture ingress and contamination.
Outer Packaging: Rolls are placed in strong corrugated boxes or crates for additional protection.
Labeling: Each package is labeled with relevant information such as material grade, thickness, width, roll length, batch number, and manufacturing date.

Storage

Temperature: Store in a cool, dry place with a temperature range of 15-25°C.
Humidity: Maintain a relative humidity of 40-60% to prevent condensation and corrosion.
Handling: Use appropriate equipment for handling rolls to avoid physical damage.
