Two reasons and solutions of ink falling off in the process of antistatic bag making
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://m.switzerland-hotel.com/
