摘要：
Plastic bags, rolls of plastic bags, and tubular blown film processes for making rolls of plastic bags. The rolls of plastic bags include a tubular blown film with a plurality of perforation lines along which plastic bags are separated from the roll. The perforation lines are formed so that portions of the lips of the plastic bags are offset from each other. The offset portions of the lips facilitate opening of the bags.
