Metal foil was first used as a seal decoration and anti-counterfeiting display for special beer bottles about 100 years ago. The "foil" material in today's beer label packaging is mainly high-content pure aluminum. Traditionally, metal foil has been used with lead or tin-plated lead, so aluminum foil is still called tin foil in China. The advantages of aluminum foil are easy processing, good printability and lamination performance, and compared with paper labels, it will not affect printing and labeling due to silk flow. The product currently used is 8011 O state, 0.0115mm foil.

Technical parameters of aluminum foil for beer seals:

Chemical composition of aluminum foil for beer labels:

Features of aluminum foil for beer labels:

1. Lightweight and flexible: Aluminum foil is light and flexible, easy to process and attach.

2. Corrosion resistance: Aluminum foil has excellent corrosion resistance and can effectively protect beer from the influence of the external environment.

3. Oxygen and light isolation: Aluminum foil can isolate oxygen and light to prevent the ingredients in beer from deteriorating due to oxidation or ultraviolet radiation.

4 Beautiful and high-end: Patterns and text can be printed on the surface of aluminum foil to enhance the product grade and visual effect.

Process flow of casting and rolling billet to produce aluminum foil for beer labels:

Casting and rolling melting → composition adjustment → static furnace refining → online degassing → adding grain refiner - filtering - casting and rolling → cold rolling - heat treatment at intermediate thickness - aluminum foil rolling - double rolling - finished product slitting - finished product heat treatment - inspection and packaging.

Surface quality of aluminum foil for beer seals:

1. There are no roller marks, black lines, bright spots, or grinding wheel marks on the surface of the aluminum foil.

2. The surface of the aluminum foil is clean, without wrinkles, slits, scratches, light and dark lines, rubber roller marks, vibration marks, diagonal lines, etc.

3. The surface of the aluminum foil has high flatness and few pinholes.

4. There is no oil stickiness, yellow oil spots, or bubbling on the surface of the finished aluminum foil after the burning of lubricating oil.

Aluminum foil packaging for beer seals:

There are large roll packaging and wooden box packaging.

Large roll packaging: The size of the large roll is determined by the width and length customized by the customer.

Wooden box packaging: The approximate size of the wooden box is: 1.4 meters long, 1.3 meters wide, and 0.8 meters high. The customer's requirements for the width and roll diameter of the aluminum foil are the determining factors of the wooden box size.
