How to measure the size of the object bag?

How to measure the size of the object bag? How to measure the object the size of the bag has been one of the most important question when designing packaging size. If the bag design, small things fit, design the added cost, thus to find the most suitable size range is especially important. So how to measure? How according to the loading goods to measure the size of the packaging design? First whether product appearance rules, the product as a cube, the cube to just can accommodate the size of the product, is roughly measure the dimensions of the cube, and then estimates bags to load the product quantity, will have a number of cube stacked up to calculate the total width is high, then leave the redundant space length, can measure the size of a packet is probably of need. Then design the size of the time to consider what aspects? What principles involved? Below we from several aspects to answer how to measure the size of the bag body: 1. The demand for packaging & ndash; 2 size design direction. The capacity of redundant & ndash; The specification of the 3 dimensional design. Human body engineering & ndash; Size design details of the specific analysis 1 bags needs a packaging capacity is limited, corresponding to different demand design direction is different also. （ 1) If supermarkets use of plastic shopping bags, so their size design direction is to put some more things at the same time as soon as possible size and not let the customer produce inconvenience when carrying action, to hold the weight of the biggest also won't let customers hand too tired. （ 2) If it is the gift of plastic shopping bags, plastic bags size is considered a packaging bag will not too big, how many goods such as tea packaging design can just load the two boxes of tea, but leave a little space, not overweight, so also convenient. （ 3) If it is a type of the plastic shopping bags, clothing because clothing is relatively light, and the average under the condition of a customer too much clothing, clothing bags are generally designed to be relatively large, the first is to consider a brand image and influence, if the bag is bigger, attention to the increased risk, at the same time, big bag and administrative levels and other types of bags away; The second consideration is part of the customer to show off the psychological, many customers are buying after the goods was carrying a big bag, there will be others & other; Bought so many must be very rich & throughout; Ideas, so this part can meet the customers' psychology. Different requirements of different size: 2 capacity redundancy design must be considered when the size is the capacity of redundancy design, because the design could not press completely fit into the size of the design, otherwise the production error, may lead to goods can't load or loading is difficult, lead to the packing costs. Therefore assume that an item is 250 mm * 350 mm * 10 mm, then the corresponding design should be more than this size, then the capacity should be designed for 270 mm * 370 mm * 20 mm, according to the specific style to convert size plastic bags. Capacity of redundant: 3 ergonomics any products need to use to consider the human body engineering, the person is taken into account in design of comfort and work efficiency. Packaging design also is so, so in terms of size, if it is a shopping bag, should consider carrying comfort, such as bag size is larger, pay attention to the not too long, bag of people carrying not mop the floor, and article bag should be long enough to let a person can carry on the shoulder.
