What Is Used For Making Aluminum Seal Cap

 Aluminum seal caps come in a variety of styles and widths. It offers stability and stiffness compared to other materials. Aluminum caps and closures are frequently used in the food and beverage industry. The aluminum lid has a sturdy construction and is easy to open.

Aluminum caps and closures are made to suit the dimensions of bottles, containers and jar mouths. The aluminum bottle cap material is aluminum alloy sheet like plain or color printed aluminum sheet. Aluminum covers of different specifications need to be produced with aluminum alloy plates of different specifications.

Advantages of aluminum bottle caps

1. The aluminum cap is hygienic, will not rust, and is easy to open without the need for auxiliary tools. After opening, the bottle cap is destructive and can effectively prevent theft.

2. The aluminum cap has the advantages of good cushioning, shock resistance, heat insulation, moisture resistance, chemical corrosion resistance, etc. It is non-toxic, non-absorbent, does not cause dust or peeling, and has very good sealing performance.

3. The aluminum cap is resistant to high temperatures, boiling, alcohol, etc. The pattern design can use color printing, embossed characters, and milled characters.

4. The aluminum cap has excellent sealing properties and a larger flat surface on the cap surface, making printing of various text logos more beautiful.

Two types of aluminum bottle caps

PP caps: It refers to pilfer proof caps that are made of printed aluminum plates and liners and are sealed with a threaded bottle mouth and cannot be restored after opening and use. It is commonly used for sealing wine, soft drinks, health products, condiments, etc.

ROPP caps: It is short for Roll-on Pilfer Proof. When the closure is installed on the bottle, the threads are formed by applying a pressure roller to the closure. ROPP caps are in great demand in the beverage and food industries and are widely used in alcohol, medical, pharmaceutical, beverage, food, agrochemicals, edible oils, lubricants,etc.

Food- grade paint

Haomei Aluminum offers plain, coated and printed aluminum foil sheet for making various bottle caps. The coating and paint is of food grade. Food-grade paint is an environmentally friendly and safe paint product that is widely used in food, catering, medical, children's products and other fields that require contact with food or have high human safety requirements.

First of all, food-grade environmentally friendly paints strictly follow relevant laws, regulations and standards in terms of ingredients. They usually use harmless, low-volatile organic solvents and do not contain harmful substances such as formaldehyde, heavy metals, benzene, etc. It has passed a number of quality and safety certifications, such as European REACH regulations, US FDA certification, Chinese GB 4806.1 standards, etc., ensuring its safety for human health.

Secondly, food-grade paint causes less environmental pollution during the construction process. Due to its use of low-volatility solvents, it can reduce the emission of harmful gases, reduce the risk of air pollution, cause less pollution to the construction site and the surrounding environment, and is conducive to the protection of indoor air quality.

In addition, food-grade paint has good durability and adhesion to the painted items after use. It can effectively protect the surface of the coated items, prevent damage caused by moisture, stains, etc., and extend its service life.

It also performs well in terms of painting effects, providing a wide range of color choices and gloss to meet different painting needs. The white painted aluminium sheet is a popular choice. At the same time, it also has good water resistance, oil resistance, wear resistance and other properties, allowing the painted items to maintain a good appearance during long-term use.

Finally, food-grade paints are widely used in food, catering and other food-contact fields. For example, in food packaging, food processing equipment, restaurant kitchens, food display cabinets and other occasions, the use of food-grade paint can ensure that painted items will not contaminate food and ensure food safety.

The Popular Sizes of Painted Aluminum Sheet

 The pre painted aluminum sheet is aluminum sheet whose surface has been coated and colored. Because it has good flatness, corrosion resistance, decoration and mechanical properties, it is favored by the market and is widely used in architectural decoration, food packaging, electronic appliances, printing, transportation and other fields.

Sizes

1. Painted aluminum sheet 5x10: It refers to 5’ and 10’ respectively, that is 5 foot and 10 foot. Its size in the unit of mm is 1524mm x 3048mm.

2. Colored aluminum sheet 4x8: It represents 4 foot and 8 foot, that is 1219 mm x 2438 mm.

3. Coated aluminum 4x10: Its another popular name is aluminum sheet 48” x120”. Its size is 1219 mm x 3048 mm.

Aluminum size	Equivalent name	Foot	Millimeter
4x8 aluminum sheet	4’ x8’ aluminum sheet	4ft x 8 ft	1219 mm x 2438 mm
4x10 aluminum sheet	4’ x10’ aluminum sheet	4ft x 10 ft	1219 mm x 3048 mm
4x12 aluminum sheet	4’ x12’ aluminum sheet	4ft x 12 ft	1219 mm x 3658 mm
5x10 aluminum sheet	5’ x10’ aluminum sheet	5ft x 10 ft	1524 mm x 3048 mm
5x12 aluminum sheet	5’ x12’ aluminum sheet	5ft x 12 ft	1524 mm x3658 mm

Thickness

The thickness of the pre painted aluminum sheet is mainly related to the coating equipment. The usual coating equipment can process the color coated aluminum sheet with a thickness of 0.3-1.2 mm. The coated aluminum plate with such thickness range can satisfy most uses.

The painted aluminum sheet thickness can be divided into three parts: substrate thickness, coating paint thickness, and protective film thickness. Generally, the thickness of the single-coated paint film is around 15um, the thickness of the double-coated paint film is around 25um and the thickness of the paint film of the back coating is around 5-8um. The thickness of the protective film is usually 0.05 mm, and PE protective film is generally used.

Medium-viscosity or high-viscosity protective film is more suitable for the protective film of the color coated aluminum sheet which can avoid scratches in the process of pressing, bending or shearing.

Main Application

The pre painted aluminum sheet for roof is coated with a layer of fluorocarbon paint or polyester paint, which makes the aluminum plate have excellent characteristics such as UV resistance, acid and alkali resistance, and high weather resistance. The common alloys are 1100, 3003, 3004, 8011, 3105, 5052, etc. The thickness range is 0.18-2.5 mm. The common width 1000 mm, 1200mm and 1250 mm.

What are the advantages of the painted aluminum sheet? Compared with the ordinary aluminum sheet, it has the following features:

1. The texture is clear and beautiful, with a sense of fashion and technology.

2. It has excellent weather resistance, no deformation and long-lasting bright color.

3. It is of strong decoration, convenient installation and wide application.
