Usually the more prestigious the packaging bag, the thicker the paper. Also the grammage and thickness of the paper material have a huge impact on the bag's endurance. Usually 157gsm (6-8pt), 210gsm (10-11pt) paper is recommended for the paper bag. And 300gsm (15-17pt) or above art pape can be used when a heavy duty packaging and carrying bag is in need. The units to represent the paper grammage and thickness are quite confusing. People in China, Australia would like to use the grammage to measure the paper thickness, while the unit pt is used in North America. Source: https://www.fortuneprintings.com/paper-bags/

How to choose the right mask for you

  The ability of the mask to fit snugly against the wearer's face determines whether or not the mask will actually work in real combat.All masks leak to a greater or lesser degree when worn on the face, and no mask is absolutely airtight.   However, if it becomes apparent that the mask will not fit the face, a large amount of dirty air will continue to flow between the wearer's breaths, thus rendering the protection ineffective. Each time you put on the mask, check the airtightness of the mask according to the instructions for use (consider the sticker). If it is obviously not tight, do not use it! https://www.unisourcesgroup.com/news/95.html

How can we make the inquiry easier in carton wholesale?  Carton wholesale, clear their purchase intention. Including: product parameters (specification, shape, material), quantity, process requirements (such as printing, gilding, film, etc.), delivery city (whether delivery?) Does it include tax? , finally it is the settlement method. Carton wholesale do not hide information from suppliers. For some industries, the cardboard box usage rate is not high, the purchase of cardboard box for this piece of understanding is not much, even if there are samples, can not tell the supplier material and other information, can only say the size; For such an inquiry, the supplier should understand and communicate with more patience.
