Two reasons and solutions of ink falling off in the process of antistatic bag making
1. Cause: there is ink in the heat seal. Solution: in the heat seal should avoid the existence of ink.
2. Cause: poor heat resistance of ink. Solution: choose the ink with good heat resistance. 3. Reason: use grid type heat sealing tool. Solution: 1. Use flat heat sealing tools. ② Paste a piece of PTFE sheet under the heat sealing tool. 4. Reason: for the aluminum foil composite material, even if the surface layer is not softened, the AC agent and printing ink have melted, so the film-like fall off. Solution: 1. Anti static bag use heat-resistant AC agent and printing ink. ② Reduce the heat sealing temperature and prolong the heat sealing time.
Packaging bag knowledge: a simple method to identify the toxicity of food packaging bags
Water detection method: put the plastic bag into the water, the non-toxic plastic bag can float out of the water, but the toxic plastic bag does not float upward.
Hand touch detection method: touch the plastic bag with your hand, if it has smooth feeling, it is non-toxic, otherwise it is toxic.
Slap detection method: hold one end of anti-static bag by hand and pat it hard. If the sound is clear and crisp, it is non-toxic, otherwise it is toxic.
Fire detection method: a plastic bag can be cut to one side and burned with fire. Toxic ones are not easy to burn, and non-toxic ones are easy to burn in case of fire. http://www.dgbpk.com/
