Harmful components that produced from sealing Poly ethylene bags
Dears,
Does anyone had an experience with sealing poly ethylene bags ? I heard that there are harmful components that similar to DPA into the chemical structure (which is a pesticide) and this un acceptable for the food contact packaging material, if this is true, is there a list with these harmful components and limits according to FDA, EFSA?
Thanks for your concern and help!
Hi Yousuf
the following table clearly state that poly ethylene bags pose no known health risk See no 4. Having said that please read the following article for more info
Which plastics are which?
Some plastics are safer than others. Use this table to see which ones are best avoided.
Identification code Type of plastic Uses Risks 1 Polyethylene terephthalate (PET)- Bottles used for water and softdrinks
- Jars for products such as peanut butter
- Lightweight and 'green' wine bottles
- Bottles used for milk and cream
- Yoghurt cups
- Bags that line breakfast cereal packets
- Shrink and cling wrap
- Clear plastic containers for fresh fruit or takeaway sandwiches
- Some soft drink bottles
- The gaskets that form a seal on screw-cap glass jars
- Take-away containers
- Waterproof coating on milk cartons
- Bags used for bread and frozen foods
- Cling wrap
- Bottle caps
- Yoghurt and margarine containers
- Food storage boxes
- Plastic cutlery
- Drinking cups and yoghurt cups
- Cups for hot coffee (polystyrene foam)
- Lightweight trays used by supermarket to package and sometimes vegetables (polystyrene foam)
- Bottles for sauces and condiments
- Babies' feeding bottles and infants' drinking cups
- Reusable water bottles for cyclists and athletes
Thanks Khan for your help!
But still i have an inquiry about the harmful components that could be residue from sealing polyethylene bags (Low density polyethylene bags) by high temperature?
for component called BPA, what is the limit of it and is it can be produced from sealing with high temperature (more than 150 C).
Kind regards
Mohamed

Just curious, how on earth can the sealing heat make azotic (DPA) or aromatic (BPA) compounds from long alkylic PE macromolecules?
If there are hazardous byproducts, they likely came from the stage of PE resin production. Collecting MSDSs and CoAs of materials can reveal some other components. The fabrication of PE film sheets or bags hardly creates any addition chemicals because of the inert nature of PE.

I'm not an expert into the poly ethylene industry but i heard that there are by products produced from sealing low density poly ethylene bags by high temperature more than 150 degrees , so i asked to know from if this is real or not ? and if it was real, what is the limit of it according to FDA or EFSA?
