There are quite a lot of choices of materials for thermal insulation bags, and each material has its own unique characteristics and applicable scenarios. The following is a detailed analysis of common materials for thermal insulation bags:
Polyethylene:
Features: low price, short life, and average thermal insulation effect.
Applicable scenarios: Due to its low cost, polyethylene is often used to make disposable thermal insulation bags or thermal insulation bags that need to be replaced frequently, such as lunch bags, water bags, etc.
Polyester:
Features: It is light, economical, easy to clean, and has good thermal insulation effect.
Applicable scenarios: It is often used in households, such as keeping meals warm. The durability and thermal insulation of polyester make it a popular choice.
Neoprene:
Features: good thermal insulation performance, light weight, soft and durable, and waterproof, wear-resistant, and non-slip.
Applicable scenarios: Neoprene is often used in outdoor sports, travel and other occasions because it not only has good thermal insulation effect, but also can adapt to various environments.
Aluminum foil material:
Features: Aluminum foil material has certain thermal conductivity, but also has very good heat insulation and moisture resistance.
Applicable scenarios: Aluminum foil insulation bags are highly adaptable to various occasions and can be used to fill beverages, dairy products, coffee, etc.
Foam material:
Features: Foam materials are divided into two types: polyethylene and polyurethane. They are light, not easy to break, and can effectively insulate.
Applicable scenarios: Foam materials are often used in incubators, food boxes, pharmaceutical packaging and other occasions that require long-term insulation. Among them, polyurethane foam materials have better insulation performance, but the price is also higher.
Bubble film material:
Features: Bubble film material is a light and soft insulation bag material with quite good insulation and buffering effects.
Applicable scenarios: Bubble film material is suitable for fresh insulation bags, express insulation bags, cake fresh-keeping bags and other occasions, which can effectively protect the safety of items during transportation.
Non-woven fabric + aluminum film pearl cotton:
Features: It combines the softness of non-woven fabrics and the insulation performance of aluminum film pearl cotton, and is a common composite material.
Applicable scenarios: This material is very common in the market, especially as a material for thermal insulation bags for corporate promotional gifts.
Stainless steel:
Features: Although stainless steel is not a common material for thermal insulation bags, it has a beautiful appearance and a long service life, and can store hot drinks such as hot water and tea.
Applicable scenarios: However, due to the strong thermal conductivity of stainless steel and the high shell temperature, it is not suitable for long-term carrying.
Food-grade materials:
Features: Food-grade materials such as food-grade PEVA, food-grade PP, etc. are non-toxic, harmless, odorless, safe and environmentally friendly, and can be directly in contact with food.
Applicable scenarios: These materials are one of the safest materials for thermal insulation bags, suitable for users who have high requirements for material safety.
