PP thermal insulation bag, a new technology to help keep food warm and fresh

PP thermal insulation bag is a multifunctional, environmentally friendly and practical insulation bag. It adopts advanced thermal isolation technology and can effectively keep the temperature of food for a long time. The design concept of this product not only focuses on temperature control effect, but also pays attention to environmental protection and safety, ensuring that food can remain fresh and safe during distribution and storage.
The biggest feature of PP thermal insulation bag is its excellent thermal insulation performance. Through the unique material ratio, the built-in 2/3/4 mm EPE aluminum foil foam layer can effectively block the conduction of external heat while maintaining the stability of the heat inside the bag. This makes PP thermal insulation bag an indispensable tool for take-out food, fast food or camping picnics. It can not only keep the temperature of food, but also delay the temperature change of food, ensure the warm taste of food during transportation, and avoid the taste change caused by too low or too high temperature.
In addition to the thermal isolation effect, PP thermal insulation bag also has a very good refrigeration effect. This bag can effectively isolate external heat in a low temperature environment, so that cold drinks, ice cream, refrigerated food, etc. can remain fresh for a long time at a lower temperature. This feature makes it not only suitable for the insulation of hot meals, but also widely used in the preservation of refrigerated foods, greatly expanding its scope of use.
The innovative design of the PP thermal insulation bag is not only reflected in its thermal isolation effect, but also in its multi-layer material structure. The bag adopts the following structural ratio: the outer layer adopts 110G/120G PP non-woven fabric or woven fabric, which has good durability and tensile resistance, can withstand large loads, and ensure that the bag is not easily damaged during use. The middle layer adopts 2mm aluminum foil foam coating, which further enhances the insulation effect by reflecting heat radiation and isolating the external temperature. The aluminum foil material can effectively reflect heat and play a role in blocking external heat sources, ensuring that the temperature of the food in the bag is not affected by external changes. The inner layer uses 0.063mm PET aluminum foil coating plus 1mm EPE foam, plus 0.05mm LDPE plastic film, which further enhances the effectiveness of the insulation layer, so that the bag can effectively prevent water evaporation while maintaining the temperature difference between the inside and the outside, keeping the food moist and fresh.

Application fields of PP thermal insulation bags
Due to its excellent performance, PP thermal insulation bags have been widely used in many industries and scenarios, especially in the following fields:
Takeaway delivery industry: PP thermal insulation bags have become a must-have tool for takeaway merchants and deliverymen due to their excellent insulation effect. Whether it is fast food, barbecue, hot soup or other food that needs to maintain temperature, the use of PP thermal insulation bags can ensure that the food maintains the best taste and temperature during the delivery process, enhancing the customer's dining experience.
Fast food and convenience food: PP thermal insulation bags are also suitable for the insulation of fast food and convenience food. For example, in fast food chains, supermarkets selling ready-to-eat meals and other places, PP thermal insulation bags can ensure that the food always maintains the ideal temperature from the kitchen to the table, avoiding the taste of the food due to low temperature.
Camping and picnics: Camping and picnics usually require carrying food and exposing it to the outdoor environment for a long time. How to ensure that the food is not affected by the temperature on the way and remains fresh and delicious? PP thermal insulation bags are designed for this purpose. Their excellent heat preservation and refrigeration functions can meet the needs of long-term outdoor activities, ensure the appropriate temperature of food, and provide a better outdoor dining experience.
Storage of cold drinks and chilled foods: In addition to the heat preservation of hot foods, PP thermal insulation bags also perform well in the storage of cold drinks and chilled foods. Cold drinks, ice cream and other foods are usually very sensitive to temperature. The use of PP thermal insulation bags can effectively delay their temperature rise and prevent them from melting during transportation. The preservation effect is particularly significant for chilled foods, which can ensure the freshness and taste of food during long-distance transportation.
