There is a good news, one of my friends starting a new business in Sweden and looking for realiable zip lock bag factories in China that produce quality pieces of zip lock bag. As you are new to this site, I suggest you to buy from wholesaler or have an agent.Buy from zip lock bag wholesaler, they have enough styles for you to start and not a MOQ(Minumum Order Quantity) limit. to have more styles for you to start would be better to start the market, but zip lock bag factories would required a big MOQ that you can not afford to.From zip lock bag agent, they can let you know how to start to import, and get reseanable prices.and avoid any lost on your first import business. From http://www.niceindustry.co.uk/about.asp And try to avoid famous brand(there's scammers on this side), you can search on alibaba to find the above two kind of zip lock bag suppliers to start or other search engine like google, yahoo,etc.
