We owe the invention of the custom plastic bags we know today to Swedish engineer Sten Gustaf Thulin. He created a strong bag by welding and die-cutting a flat tube of plastic in the early 1960’s for a packaging company in Sweden. Today, his simple idea has been translated into countless custom plastic bags around the world- such as the 12" Colored Die Cut Custom Plastic Bag and the 15 inch Colored Die Cut Custom Plastic Bag- designed to carry all sorts of goods everywhere from grocery stores to trade shows. And did you know that, compared to paper bags, custom plastic bags consume 40 percent less energy, generate 80 percent less solid waste, produce 70 percent fewer atmospheric emissions, and release up to 94 percent fewer waterborne wastes? Plus, the custom plastic bags and all other promotional bags that you will find in the promotional products industry are made to be reused, meaning more exposure for your brand, and less harm to the environment.
