What Is Used To Make Aluminum Ropp Cap

 Ropp cap is a threadless aluminum cap used to seal glass bottles. ROPP caps are in great demand in the beverage and food industries and are widely used in alcoholic beverages, medical, pharmaceutical, beverages, food, edible oil, etc.

Carbonated soft drinks, energy drinks and alcoholic beverages are the main end-user areas of aluminum bottle caps and closures. In addition, the use of aluminum bottle caps in the wine industry is becoming more and more popular, as aluminum screw caps can better isolate oxygen from wine and are cost-effective compared to corks.

Aluminum cap for bottle is mostly processed on production lines with a high degree of automation, so the strength, elongation, dimensional deviation and other requirements of the bottle cap material are very strict, otherwise there will be fractures or creases during processing. The common alloys are 8011 aluminum foil.

The main elements of 8011 aluminum foil are Al-Fe-Si, and the rest are trace impurity elements. Its performance is better than pure aluminum foil. 8011 aluminum plate is not commonly used, but 8011 aluminum foil is widely used, especially in the field of bottle cap materials. 8011 aluminum foil is the main material for PP/ROPP bottle caps.

The composition and organization of the alloy determine the performance of the alloy. According to the role and mutual influence of the main alloying elements of the 8011 alloy, the main alloying element Fe content of the 8011 alloy is selected to be controlled at about the middle and upper limit of the alloy standard range (0.8%) to reduce the earing rate of th ealuminum alloy plate and improve the strength of the alloy.

At the same time, the Si content is controlled at about 0.75%, and the Fe/Si ratio of the alloy is reasonably selected (approximately equal to 1), which lays a good foundation for the subsequent correction of the alloy to obtain an ideal texture morphology.

8011 aluminum foil sheet can have different surface treatment like DOS oil coating, painting or color printing. All the used coating is of food grade. Food-grade environmentally friendly paint has good durability and adhesion to the coated objects after use, and can effectively protect the surface of the coated objects, prevent damage caused by moisture, stains, etc., and increase their service life.

8011 Aluminum Cap Material

As a green bottle cap material, aluminum is more and more demanding. 8011 aluminum foil is a main kind. How much do you know about it? Let’s have a look.

8011 aluminum foil can be used as the raw material of anti-counterfeit aluminum bottle caps. It can be divided into casting and hot rolling. It also has different tempers such has H16 and H18, which can satisfy the requirements of different industries.

8011 H18 bottle cap material

8011 H18 bottle cap material is mainly applied to stamping shallow caps, which can be cast and rolled. The process: cold rolling-foil rolling-straightening-slitting-packaging and other processes. It does not require annealing treatment, so the production period is the shortest and the price is relatively cheaper.

8011H16 bottle cap material

8011H16 bottle cap material is an important member of hot-rolled aluminum anti-theft cap material. Its specification:

• Thickness range: 0.15-0.27mm
• Thickness tolerance: ± 0.005mm
• Width: 330-1000mm
• Width tolerance: ± 1mm
• Tensile strength: 150-165Mpa
• Elongation rate> 2%

As for its quality, it should be of smooth surface, no obvious roll marks, no obvious defects such as oil stains, scratches, bright strips, etc. The earring rate should be less than 3%.

Its production needs more steps: cold rolled-annealing-foil rolled-stretch bending-slitting. After the finished rolls are produced, they must go through a number of processes such as cutting, painting, drying, multiple stamping, and anti-counterfeiting markings to produce qualified bottle cap materials. For medical caps and wine bottle caps, there are some difference in the process of annealing.
