گرمی سگ ماہی ایلومینیم ورق کیا ہے؟?
ہیٹ سیل کرنے والا ایلومینیم ورق ایک ایلومینیم ورق ہے جس پر خاص گرمی سے متعلق حساس کوٹنگ لیپت ہوتی ہے۔. ہیٹ سیلنگ فوائل میٹریل میں کثیر پرت کا ڈھانچہ ہوتا ہے اور یہ اکثر ایلومینیم فوائل کمپوزٹ میٹریل سے بنا ہوتا ہے جو گرم اور دبانے پر دوسرے مواد کے ساتھ جڑ سکتا ہے۔. This process can form a tight and durable seal and is often used in packaging applications to preserve products and ensure they are not contaminated. Common combinations of heat sealing aluminum foil include polyester (PET), ایلومینیم ورق (AL) and a heat sealing layer (such as PE). This three-layer structure combines aluminum foil composite materials with good sealing performance and strength, suitable for various packaging needs.
گرمی سگ ماہی ایلومینیم ورقStructural composition of heat sealing aluminum foil
Heat sealing aluminum foil is usually made of aluminum foil composite materials, and the multi-layer structure is composite, which has great advantages in application.
| Heat-sealing Foil Structural Characteristics |
| Structural Layer | Material Composition | Composition Function |
| Outer Protective Film | The outer layer of the heat-sealed foil is usually a transparent polyethylene (PE) or polypropylene (PP) film. | Its main function is to protect the inner layer from pollution, damage or moisture intrusion. |
| Printing Layer | It is usually a layer of polymer film that has been specially treated. | It is used to print text, images or logos to meet the needs of packaging design. |
| Aluminum Foil Layer | The core part of the heat-sealed aluminum foil. | It provides gas and water vapor barrier properties and has excellent thermal insulation properties. Aluminum foil is usually thin, but it can effectively protect the items in the package. |
| Adhesive Layer | Located between the aluminum foil layer and other film layers, the adhesive layer can be hot melt adhesive, pressure-sensitive adhesive or other types of adhesives. | It is used to bond different layers of materials together to ensure the integrity of the heat-sealed aluminum foil. |
| Heat-sealing Layer | Located on the outer layer of the heat-sealed aluminum foil, it is usually made of thermoplastic materials such as polyethylene (PE) and polyester (PET). | It can bond with other materials after heating to form a tight seal. The quality and performance of the heat-sealing layer are crucial to the sealing effect of the heat-sealed aluminum foil. |
Application of heat-sealed aluminum foil in packaging
Heat-sealed aluminum foil is widely used in the field of food packaging, such as the packaging of dairy products (fresh milk, yogurt, وغیرہ), as well as the packaging of pre-prepared dishes, pastry foods, وغیرہ. Due to its excellent sealing and barrier properties, it can effectively prevent food oxidation, deterioration and contamination, and ensure the safety and hygiene of food. Heat-sealed foil has excellent compatibility and can also be well used in milk container caps.
