Product Details

High barrier aluminum foil insulation bag is an upgraded high-performance insulation packaging based on traditional aluminum foil insulation bags. Its core advantage lies in the use of multiple layers of high barrier materials to significantly enhance its ability to block gases, moisture, and heat, thereby extending the cooling or insulation time. It is suitable for medium to long distance transportation, storage and distribution of high-value foods (such as fresh produce and dairy products), or temperature sensitive items (such as vaccines and biological reagents). Its characteristics are long insulation time, strong sealing, and good puncture resistance.

The outer layer is made of tear resistant CPP film (cast polypropylene) or Oxford cloth, with a thickness of 20-50 μ m, which has wear-resistant, waterproof, and puncture resistant properties. Some styles are coated with anti UV coating;

The high barrier layer uses EVOH (ethylene vinyl alcohol copolymer) film or aluminum-plastic composite film (thickness 0.02-0.05mm), which has a barrier rate for oxygen and water vapor 10-100 times that of ordinary PE film, reducing heat exchange caused by gas permeation;

The insulation layer uses pearl cotton (EPE, thickness 5-10mm) or XPE foam cotton, which locks in air through a closed cell structure, reduces heat conduction efficiency, and has better insulation performance than traditional bubble wrap;

The inner layer uses food grade aluminum foil (thickness 0.012-0.02mm) with high reflectivity (≥ 95%) to block infrared radiation, while forming a "double barrier" with a high barrier layer;

The sealing structure is mostly a combination of zipper and Velcro (some high-end models come with silicone sealing rings), or hot pressed sealing edges to ensure that the air inside the bag does not circulate and strengthen the barrier effect.

Product Parameters

● High barrier layer material:
EVOH film (0.02-0.03mm) has the best oxygen barrier properties and is suitable for foods that require oxidation prevention, such as meat;
Aluminum plastic composite film (0.03-0.05mm) has high cost-effectiveness and balanced comprehensive barrier properties

● Insulation layer material: pearl cotton (5-10mm), XPE foam cotton (3-8mm)
XPE foam cotton has a higher density, better insulation than pearl cotton, and good resilience, making it less prone to deformation

● Inner layer material: food grade aluminum foil (compliant with GB 4806.11)+heat sealing adhesive. The aluminum foil needs to pass heavy metal testing, and the heat sealing adhesive needs to be resistant to high and low temperatures (-40 ℃ to 120 ℃) to avoid detachment

● Dimensions (length x width x height):
30 × 20 × 15cm (small, containing vaccines/samples)
50 × 35 × 25cm (medium, containing 2-3kg fresh food)
70 × 50 × 30cm (large, containing 5-10kg of ingredients)
The larger the size, the more ice packs/baby warmers need to be used to avoid uneven internal temperature

● Sealing method: Nylon zipper+Velcro, silicone sealing ring+press button. The silicone sealing ring has the highest sealing level (can be tested underwater without air leakage) and is suitable for rainy or humid environments

FAQ

Q: What is the core difference between high barrier aluminum foil insulation bags and ordinary aluminum foil insulation bags?

A: The core difference lies in the "high resistance layer": ordinary models rely solely on aluminum foil and bubble wrap for insulation, while gases and water vapor can slowly penetrate, and the insulation time is usually less than 6 hours; The high barrier version uses EVOH or aluminum-plastic composite film to block penetration, combined with a thicker insulation layer, which can last up to 8-24 hours and maintain a more stable temperature (fluctuation ≤ 3 ℃).

Q: Can it be used for transporting drugs that require strict temperature control, such as insulin?

A: Sure, but you need to choose a dedicated model with a temperature recorder (some high-end models have built-in NFC chips that can view temperature curves in real time), and use a phase change ice pack (maintaining 2-8 ℃). When the ambient temperature is ≤ 30 ℃, the temperature control time can reach 12-16 hours, meeting the needs of short distance transportation.

Q: Will the insulation effect decrease after multiple uses?

A: If the insulation layer (pearl cotton/XPE) is not damaged and the sealing structure (zipper, sealing ring) is not aged, it can be reused more than 50 times with a decrease in insulation effect of no more than 10%; If the zipper is found to be stuck or the sealing ring is deformed, it needs to be replaced in a timely manner, otherwise the sealing performance will decrease and the insulation time will be shortened.

Q: How to clean and maintain?

A: The inner aluminum foil can be wiped with a damp cloth (avoid using steel wire balls to prevent scratches), and the outer Oxford cloth can be washed with water (water temperature ≤ 30 ℃, do not expose to direct sunlight to avoid material aging);
When not in use for a long time, it is necessary to air dry and store it open to avoid folding and causing deformation of the insulation layer due to compression.

Q: How much higher is the cost compared to the regular model? Is it worth buying?

A: The unit price is usually 3-5 times that of ordinary aluminum foil insulation bags, but due to their reusability, the cost per use is actually lower. If frequent transportation of temperature sensitive items such as fresh produce and pharmaceuticals is required, or if long-term insulation is pursued, the cost-effectiveness is higher.
