After the plastic packaging bags are ready to be filled with products to be sealed before they can be put on the market, so what should be noted when sealing, how to seal the mouth firmly and beautifully? Bags do not look good again, the seal is not sealed as well as the appearance of the bag will have an impact. So what should we pay attention to when sealing plastic packaging bags?
1. Single-layer plastic packaging bag sealing method
Ordinary plastic packaging bags are single-layer, such bags thin, low temperature can be sealed firmly, the temperature will be high after the bag will be burnt, so when sealing must be repeatedly tested temperature, until the temperature will not be burnt and the bag surface is flat, so the temperature is the right temperature. Usually such bags are selected by the foot sealing machine.
2. Multi-layer composite packaging bag sealing method
Multi-layer composite plastic packaging bags due to the combination of multi-layer materials, the bag is thicker, and PET is only high-temperature resistant, so such bags can withstand relatively high temperatures, usually to reach 200 degrees before the bag can be sealed, of course, the thicker the bag temperature to be higher, when encapsulated must be tested and then sealed in bulk to avoid unnecessary trouble in the process of use.
Plastic packaging bag sealing is the main thing is the temperature control, temperature control is good sealing flat, beautiful, will not break, so sealing must test a suitable temperature, must not be in a hurry to mass production to avoid waste.
Ate outside of the bag sealing problem, you also need to pay attention to the bag if used for food packaging whether there will be odor? Food bags with a pungent smell can still be used?
We often smell some pungent smell when using food bags, especially when buying vegetables and some cooked food products, can these bags with pungent and irritating smell be used? With such bags on our body will have what bad effects?

Small traders in order to save costs to use recycled material bags, recycled material production of food bags at low cost, in order to attract customers such bags are generally provided free of charge to customers to use. Long-term consumption of food packaged in these bags will produce great harm to the human body.
3. What kind of food bags can be used with confidence it
Safe and secure bags are no smell, which is what we call the brand-new material made out of bags, brand-new material made out of bags is colorless and tasteless, even if there is a smell is the taste of printing ink and the smell of plastic produced by heating in the production process, there will not be a pungent smell.
