I have big doubt on the usage of coloured LDPE bags for food packaging. Also I have seen blue coloured hairnets are used in food industries. Is there any specific reason for the usage of blue coloured bags or blue coloured materials in food industries?

Yes, theoretically so you can see them if they fall into your product!

Do you think the colours might be more susceptible for migration? For example blue hairnet giving out the blue colour when gets wet with water?

To p. ramadoss:

 

Usually the blue colour from the hair net is not easily 'leached out' and I am sure your hair net is not touching food or food contact surface, right?

 

Someone explained to me that in food industry, there is very unlikely to have food with BLUE colour. That's why most of the requirement for PPE or detectable metal plaster must be in blue.

You should be having migration tests on ALL food contact packaging regardless of colour.

 

As YongYM says, hairnets etc are coloured so that you can detect if they inadvertently fall into your product as very few food products are blue. And if you do have a blue food product (like a blue smartie) you can wear a red hair net!

Already put blue coloured hairnets in place.

Dear All,

 

Of course, the use of blue plastic also probably increases the likelihood of the material  containing recycled goods.

 

Hairnets i wouldn't know.

 

Is one also obliged to differentiate hairnets between low / high risk areas.? Matching combination with the cap perhaps?

Is it true that blue coloured LDPE are from recycled material? I mean more chances of getting recycled blue coloured packaging material?

Dear p.ramadoss,

 

AFAIK, the potential likelihood from coloured material is > than from uncoloured. The actual likelihood may depend on various factors.
