After the foil material is made, the thickness must be reduced to make the foil. This is done in a rolling mill, where the material passes through a metal roll called a work roll multiple times. When aluminum plates (or nets) pass through the rollers, they are squeezed thinner and squeezed out through the gaps between the rollers. The work roll is paired with a heavier roll called a support roll, which applies pressure to help maintain the stability of the work roll. This helps to maintain product dimensions within the tolerance range. The work roll and support roll rotate in opposite directions. Add lubricants to promote the rolling process. During this rolling process, it is sometimes necessary to anneal (heat treat) the aluminum to maintain its machinability.



Control the reduction of foil by adjusting the rotational speed of the roller and the viscosity (flow resistance), quantity, and temperature of the rolling lubricant. The roll gap determines the thickness and length of the foil leaving the rolling mill. This gap can be adjusted by raising or lowering the upper work roller. Rolling on the foil produces two natural finishes, bright and matte. When the foil comes into contact with the surface of the work roll, a bright surface is produced. To produce a matte finish, two sheets of paper must be packaged together and rolled up simultaneously; After completing this operation, the sides that come into contact with each other will eventually appear matte. Other mechanical finishing methods typically generated during conversion operations can be used to generate certain patterns.



When the foil passes through the roller, it is trimmed and cut using a circular or razor shaped tool installed on the roller mill. Trimming refers to the edges of metal foil, while slitting refers to cutting the metal foil into several pieces. These steps are used to produce narrower curl widths, trim the edges of coatings or laminated materials, and produce rectangular pieces. For certain manufacturing and conversion operations, web plates that break during the rolling process must be reconnected or spliced. Common splicing types used to connect flat foil and/or back foil web plates include ultrasonic, heat sealing tape, pressure sealing tape, and electric welding. Ultrasonic joints use solid-state welding in overlapping metals (made from ultrasonic transducer

Aluminum foil lunch boxes and containers are the best alternative to plastic tableware in the catering and takeout markets, especially for group dining units, large-scale events, and emergency support situations. In the aluminum foil lunch box scheme, the food can be completely sealed to ensure that it is not contaminated by bacteria and viruses during transportation and distribution; Food will not be spilled and the site should be kept clean. Aluminum foil has excellent barrier properties, which can effectively prevent food from spoiling in high-temperature environments. Especially in areas where people gather in large numbers, such as schools and hospitals, food safety and public health can be ensured. Sealed lunch boxes can be mixed, set, or individually packaged according to different varieties, providing consumers with a variety of combinations and choices according to their conditions.

In large-scale events and centralized dining venues, a pantry can be set up on-site for refrigeration and heating, providing meals at any time. Consumers can also heat food in various ways. After meals, aluminum foil lunch boxes can be compressed on-site for storage and transportation, greatly reducing the amount of garbage and improving disposal capacity. The continuously improving and improving community waste classification and recycling system helps to improve the classification and recycling of aluminum foil lunch boxes and containers, which can enter the urban waste recycling system until complete recycling of aluminum materials is achieved. During garbage incineration, the incineration of aluminum foil lunch boxes and containers does not produce harmful gases.

Recent scientific research has shown that compared to materials such as plastic, steel, paper, glass, and wood, the coronavirus has the shortest survival time (2-8 hours) on the surface of aluminum. This indicates that aluminum foil packaging may be the best packaging material for cold chain storage and transportation of fresh, food, and pharmaceutical equipment.

As is well known, "Wolverine" Hugh Jackman has an extreme love for coffee. Although he already owns two of his own coffee shops in New York, this does not satisfy his desire to know more about coffee. This time, he went deep into Africa, where coffee is produced, got to know coffee farmers, and even filmed documentaries for them to draw attention to poor coffee farmers. For this reason, he also established a company specifically, To transport the coffee back to the United States and sell it as capsule coffee.

The story begins in 2009 when Hugh Jackman and his wife Debora-lee Furness were invited to Ethiopia as ambassadors for the Australian World Vision, one of the world's largest humanitarian aid organizations. He is a long-term donor to the organization and wants to see the progress of community development and how rural communities fight poverty.

He met 27 year old coffee farmer Dukale there, and they met at first sight, chatting about work and family, and working together on Dukale's plantation. Seeing Dukale working day and night cannot lift his family out of poverty, and facing problems such as education and healthcare, it changed Jackman's view of the world. Dukale uses environmentally friendly methods to produce high-quality coffee beans, but can only sell them at low prices, enduring exploitation by local distributors.

After Jackman finished his journey, he returned to New York and was invited to give a speech at United Nations Climate Week, requesting world leaders to provide support for coffee growers in developing countries such as Dukale. And he kept talking to his neighbors and local coffee shops about everything he saw in Ethiopia, telling everyone to buy Fair Trade Coffee. He increasingly felt that even a small cup of coffee could contribute to changing the face of poverty in the world. Later, he decided to establish the company Laughing Man Coffee&Tea, providing coffee growers from poor areas such as Dukale with the opportunity to enter the market at higher prices.
