Insulated packaging types and applications!

on November 17, 2024

Insulation type packaging is mainly used to maintain the temperature stability of products in the process of transport and storage, suitable for food, pharmaceuticals, cosmetics and so on that need to be refrigerated or insulated. It prevents the influence of external temperature on the products inside the package and ensures that the products are within the expected temperature range, maintaining their quality and safety. Common thermal insulation packaging materials include foam, aluminium foil, vacuum insulation materials, etc., which keep the internal temperature stable by blocking heat transfer.

 

Types of insulation type packaging

 

Foam insulation box

Material: Commonly used foam materials include polystyrene foam (EPS), polyurethane (PU), etc., which have good thermal insulation performance.

Characteristics: lightweight structure, low cost, with good thermal insulation, suitable for a variety of temperature-sensitive products.

Application: food cold chain transport, medicine transport, vaccine and other perishable commodities insulation transport.

 

Aluminium foil heat insulation bag

Material: made of aluminium foil or aluminium-plated film laminated with bubble film to achieve thermal insulation effect by reflecting heat and bubble cushioning.

Features: lightweight, easy to carry, high reflectivity, can effectively block radiant heat.

Application: used for takeaway delivery, short-term insulation of food and cosmetics.

 

Vacuum Insulation Panel (VIP)

Material: composed of core material, vacuum layer and barrier layer, containing glass fibre, aerogel and other highly efficient thermal insulation materials to block heat conduction.

Characteristics: Highly efficient heat insulation, excellent heat preservation performance, suitable for long time transport with extreme temperature difference.

Application: Long-distance transport of high-value or highly sensitive products such as medicines and vaccines.

 

Ice packs and freezers

Material: bag-like material filled with water and gel, which can be repeatedly frozen or heated as needed.

Characteristics: can maintain low temperature for a long time after freezing, used as auxiliary material for cold chain transport, suitable for products that need to be frozen and preserved.

Application: Used in conjunction with heat preservation box or heat insulation bag for the refrigerated transport of food and medicine.

 

Paper heat insulation material

Material: Use honeycomb structure of cardboard or multi-layer composite paper to achieve thermal insulation effect through the pore structure.

Characteristics: biodegradable, environmentally friendly, thermal insulation performance is slightly inferior to foam and vacuum materials, but suitable for short distances and environmentally friendly requirements of the scene.

Application: short-term thermal insulation transport of fruits and vegetables, meat and other fresh food.

 

Advantages of thermal insulation class packaging

 

Temperature control

Thermal insulation packaging can ensure that the product maintains a stable temperature during transport, preventing quality degradation due to temperature fluctuations, especially for fresh food, pharmaceuticals and other temperature-sensitive products.

 

Protective performance

This type of packaging often has a certain cushioning effect, can absorb the impact of the transport process, play a double protective effect.

 

Extend product shelf life

By controlling the temperature, thermal insulation packaging can effectively extend the shelf life of perishable products and protect food safety and pharmaceutical effects.

 

Environmental friendliness (depending on the material)

Many thermal insulation materials such as paper insulation, biodegradable foam, etc. meet environmental requirements, reducing the environmental pollution caused by traditional plastic and foam materials.

 

Limitations of thermal insulation type packaging

 

Higher cost

Highly efficient thermal insulation materials such as vacuum insulation boards, biodegradable foam, etc. cost more, increasing the cost of packaging, suitable for high value-added products.

 

Large volume

Certain thermal insulation materials are thick and occupy space, increasing transport and storage costs, especially in long-distance transport, which may affect the loading capacity of goods.

 

Material stability problems

Some heat preservation materials may weaken the heat preservation effect after repeated use, or even deformation will occur, it is difficult to reuse.

 

Application areas of thermal insulation packaging

 

Food cold chain

Thermal insulation packaging is especially critical in cold chain logistics, such as fresh food, meat, dairy products, etc., to ensure that the food is transported at low temperatures to maintain its freshness.

 

Pharmaceutical industry

For temperature-sensitive medicines such as vaccines, blood products, reagents, etc., thermal insulation packaging ensures that they are transported at the specified temperature to avoid temperature fluctuations that may lead to a decrease in efficacy.

 

Electronic products

Certain electronic components are easily damaged in a high temperature environment. Insulation packaging can prevent the influence of external high temperature and ensure product performance.

 

Takeaway Delivery

With the growth of takeaway and fresh food delivery, the need for short-term insulation has increased, and insulated packaging such as aluminium foil insulated pouches are suitable for short-term insulation or cold-keeping needs.

 

Cosmetics and skincare products

Some cosmetic and skincare ingredients are temperature sensitive, and insulated packaging can ensure their temperature stability during storage and transport to prevent quality change.

 

Future trends in thermal insulation packaging

 

Environmentally friendly insulation materials

The future of thermal insulation packaging will be more biodegradable materials and renewable resources, such as plant fibre, mushroom mycelium foam, etc., to reduce the burden on the environment.

 

High-performance thermal insulation materials

The development of new materials such as aerogel and ultra-thin vacuum insulation panels can ensure efficient thermal insulation while reducing thickness, which is suitable for the transport needs of high-end products.

 

Intelligent Insulation Packaging

Through the integration of temperature sensors, RFID and other technologies, future thermal insulation packaging will be able to monitor product temperatures in real time, suitable for perishable and perishable high value-added products.

 

Multiple use and recycling

Some high-quality thermal insulation materials such as vacuum insulation board and high-performance foam will be realised for multiple use, reducing packaging waste.

 

Combined insulation design

According to different product design combination of thermal insulation packaging, through the internal and external different materials and design more flexible response to the demand for temperature control.

The application of thermal insulation packaging is expanding in various industries, especially in the modern logistics and supply chain on the protection of temperature-sensitive products play an important role. Choosing the right insulation packaging material can ensure product quality while achieving a balance between economy and environmental protection.
