The wholesale 70g self-heating pack is a specialized thermal unit designed to provide efficient, flameless heat for a variety of self-heating food and beverage containers. Weighing in at a compact 70 grams, this heating element is the powerhouse behind many portable meal solutions, such as self-heating coffee cups, instant noodles, and compact bento boxes. For distributors and manufacturers, sourcing these packs at wholesale prices is essential for cost-effectively producing ready-to-eat meals that offer convenience and warmth to consumers without the need for electricity or microwaves.

Features of Wholesale 70g Self Heating Pack

Compact Size

At just 70g, this heating pack is lightweight and small, making it ideal for use in single-serve food packaging. It takes up minimal space, allowing for slimmer product designs and more efficient shipping logistics.

Rapid Thermal Reaction

Despite its small size, the 70g pack is engineered to react quickly when activated by water. It generates sufficient heat to raise the temperature of food or beverages to a palatable level within minutes.

Consistent Heat Output

Manufactured with precise chemical ratios, these packs provide a stable and controlled heat output. This consistency ensures that the food is heated evenly without reaching dangerous temperatures that could damage the packaging or burn the user.

Bulk Availability

As a wholesale product, these packs are available in large quantities, making them an economical choice for businesses looking to mass-produce self-heating products. Purchasing in bulk significantly reduces the unit cost, increasing profit margins.

How are wholesale 70g self heating packs made?

The manufacturing process of these packs focuses on safety, chemical stability, and efficient mass production.

Material Selection

The primary ingredients, usually food-grade quicklime (calcium oxide), aluminum powder, and other thermal agents, are selected for their high exothermic properties. A non-woven fabric pouch material is chosen to contain the powder while allowing water penetration.

Precision Mixing

The chemical powders are weighed and mixed in a controlled environment to ensure the correct reaction ratio. Consistency in mixing is vital to guarantee that every 70g pack performs identically.

Packaging and Sealing

The mixture is poured into the porous non-woven pouches. These pouches are then heat-sealed to prevent the powder from leaking out. The outer packaging often includes a plastic film to keep the pack dry until it is ready for use.

Quality Control

Before wholesale distribution, samples from each batch are tested for reaction speed, peak temperature, and duration. This ensures that the packs meet safety standards and perform reliably in the final product application.

Popular Uses of 70g Self Heating Pack

Self-Heating Beverages

The 70g pack is perfectly sized for self-heating coffee, tea, or soup cups. It provides enough energy to heat a standard volume of liquid (approx. 200-300ml) to a comforting drinking temperature.

Instant Noodle Containers

Many portable instant noodle pots utilize this size of heating pack to warm the water and cook the noodles quickly, providing a hot meal solution for travelers and office workers.

Compact Food Containers

Due to its compact nature, the 70g pack is used in smaller meal kits or side dish containers where larger heating elements would be impractical.

DIY and Emergency Kits

Some survival kits include these loose heating packs along with rations, allowing users to improvise a heating method for food in emergency situations by placing the pack and food in a contained space.

How to choose wholesale 70g self heating packs?

Verify Chemical Composition

Ensure that the packs use high-quality, food-grade materials. The chemicals should be non-toxic and stable, as they will be in close proximity to food items.

Check Reaction Specs

Look for specifications regarding peak temperature and heating duration. A good 70g pack should maintain heat long enough to warm the food thoroughly but cool down safely afterward.

Supplier Reliability

When buying wholesale, choose a supplier with a proven track record of quality control. Request safety certifications and material data sheets to ensure compliance with international food safety standards.

Packaging Integrity

The wholesale packaging must be robust and moisture-proof. Since the packs are activated by water, any exposure to humidity during storage can ruin the product.

How to care for and store wholesale self heating packs?

Moisture Control

Store the packs in a dry, climate-controlled warehouse. Exposure to high humidity or rain can trigger the chemical reaction prematurely, rendering the packs useless.

Cool Environment

Keep the inventory in a cool area, away from direct sunlight and heat sources. While not highly flammable, the chemicals are best preserved at stable temperatures.

Inventory Rotation

Follow a “first-in, first-out” inventory system. Although these packs have a long shelf life, using older stock first ensures that no product loses its efficacy over time.

Safe Handling

Workers handling the packs should wear gloves and masks to avoid inhaling fine dust or getting powder on their skin, which can cause irritation in some individuals.

Conclusion

The wholesale 70g self-heating pack is a crucial component in the self-heating food industry, offering a balance of power, portability, and cost-effectiveness. For businesses, investing in high-quality wholesale heating packs ensures that their final food products deliver a reliable and satisfying user experience. By selecting the right supplier and adhering to proper storage protocols, companies can leverage this technology to expand their product lines in the convenience food market.
