1. Find a single line. Observe the sealing lines on both sides of the rice bag or flour bag. You will find that one side is sewn with a single thread, that is, the "一一一" side, and one side is sewn with a double thread, that is, the "====" side. When disassembling, the single thread is on the left hand side because the buckle is on this side. If everything goes well, grab a thread with one hand and pull it open with both hands. If the seal is sewn too tightly, use scissors to cut off the thread (the single thread on the left), pull one thread with one hand and pull it to both sides, and the seal will open.
2. Look for short heads. Observe the two ends of the rice bag or flour bag seal to see which end is shorter, start from the shorter end. The same as the method in 1. If it goes smoothly, grab a thread with one hand and pull it open with both hands. If the seal is too tight, use scissors to cut off the thread, pull one thread with one hand and pull it to both sides, and the seal will open.
3. Oral formula. The double threads are facing me, so I need to pull them from the left side, cut off the thread ends, and pull them on both sides.
Explanation: 1) Facing the double-lined side of the bag (i.e. the side of "===="); 2) Remove it from the left when removing it; 3) Then cut it close to the edge of the bag Excess thread at the seal; 4) After cutting off the thread, there will be a thread on both sides of the bag. Pull one thread with one hand and pull it to both sides, and the seal will open. :
The above three methods actually follow one rule: find one end of the buckle, and then unpack it smoothly. These three are suitable for all dismantling work of rice bags, flour bags, fertilizer bags, etc.
