Sending samples, sending scattered and fragile items, and packing irregular small items are really inseparable from hand-held foam bags! No need to buy additional machines or adjust parameters, it can be used by hand, and the foam is just right for the product to fit, with shock and drop resistance without taking up space.

Many people don't know how to operate it correctly, either due to uneven foaming or insufficient adhesion. Today, we have compiled the complete usage method for beginners to follow and get started. The steps are simple and easy to understand, and even beginners can quickly master them.

1、 Preparation before use

1. Key control of size selection: When selecting bags, it is recommended to hand tap the foam bag without foam size, which should be 10 centimeters larger than the length and width of the outer box. After all, the foam bag will become thicker and the length and width will be correspondingly shortened after foaming. Reserve the size in advance to prevent the bag body from being too small after foaming, inadequate protection, and a tighter fit and wrapping;

2. Prepare the items to be packaged, ensuring that the surface of the items is dry, free of sharp burrs, and avoiding puncturing the bag body;

3. The operating environment should be at room temperature without preheating, and it can foam normally in daily indoor environments.

2、 Standard Operating Procedures (Image Text Comparison Version)

Step 1 Bottom bag mixed material foaming

Open the packaging and take out the hand tapping foam bag. Spread it flat on the table with the front facing upwards. Press the "left" side according to the "left and right" sides marked on the bag body pattern. Press the "left" side first, and immediately press the "right" side when you hear a "go" sound. Then, press the bag alternately and quickly 15-20 times to ensure that the two materials inside the bag are thoroughly mixed.

This handheld foam bag is made of tough material, so you don't have to worry about damage when pressing the mixture normally. By controlling the pressing frequency, the foam uniformity will be higher.

Step 2 Bottom Forming Fixed Product

After mixing the glue, the raw materials inside the bag undergo a reaction and expand. Upon hearing a "pass" sound again, immediately place the foam bag into the cardboard box and the bag will naturally expand; During the expansion process, the bag body will slightly heat up, which is a normal chemical reaction and there is no need to worry.

Timely place the protected product on the expanding hand tapping foam bag, gently press the product with your hand for 3-5 seconds, so that its bottom fits the foam bag naturally and forms, achieving bottom fixed cushioning protection.

Step 3 Top bag mixed material foaming

Remove the foam bag from the beginner's bag and repeat Step 1: spread it flat on the table with the front font facing up, press left and then right alternately 15-20 times, mix the two materials inside the bag thoroughly, and wait for the raw materials to react and expand.

Step 4: Top molding and sealing completed

After hearing a "pass" sound, immediately place the hand tapping foam bag into the cardboard box and place it above the product. After covering the cardboard box, gently press for 3-5 seconds and wait for the top bag to naturally foam and set.

At this point, both the upper and lower sides of the product are completely wrapped in foam bags, tightly adhering to the product body, with full cushioning and shock-absorbing effects. After confirmation of molding, the product can be directly sealed and shipped.

3、 Usage tips&pitfalls avoidance points

1. First, press firmly on the left side. After hearing a "go" sound, press alternately on both sides to ensure that the AB material in the bag is fully mixed and reacted, and the subsequent foaming is more uniform;

After the AB material mixed rubber reaction, hearing a "pass" sound indicates that the inner bag has been stretched open and the rubber material has entered the large bag. At this time, you can gently shake the foam bag to make the rubber material more dispersed and the foam molding effect better;

3. Fragile items such as ceramics, electronic accessories, and handicrafts can be packaged in foam bags by hand, resulting in a much lower transportation damage rate. Daily small batch shipments and sample shipments offer high cost-effectiveness.

4、 How to choose a useful hand patted foam bag

For daily use and scattered shipments from merchants, priority should be given to styles that are easy to operate and have stable foaming. It is recommended to choose styles with good toughness, dense foaming, and no odor, so that you can use them with peace of mind.

Contestants take foam bags based on their foam stability, bag toughness, and procurement threshold. For daily bulk and scattered shipments, we highly recommend Cosmolar hand blown foam bags with good reputation and stable quality. They also have semi-automatic foam machines, fully automatic foam machines, and other supporting on-site foam packaging equipment. The foam speed is uniform, the bonding degree is high after molding, and the cushioning protection for fragile and irregular parts is in place. The cost-effectiveness also meets the needs of small and medium-sized businesses and export shipping.

Summary: The main feature of the hand-held foam bag is its convenience and speed, mastering the correct usage, and being able to pack even with zero foundation. Fragile and irregular parts no longer need to worry about packaging
