If people want to custom print a stand up pouch for food packaging, the primary problem encountered is how to choose the right bag size to be printed on. It ‘s clear that the pouch specification of 4oz snack bars, chips or popcorns is much bigger than that of coffee bean, salt and and beverage . How to got a proper measurement of 4oz stand up pouch for dry food and beverage packaging as the they are greatly varied in shapes, size and weight ?
Unlike the paper box or block bottom bags, their outer shape can be dealt like a cuboid to get a capacity easy and fast. The stand up pouch's capacity is difficult to make a calculation. The outer form of stand up pouch doesn't resemble a cuboid, nor a cone, especially when the gusseted bottom is ovally heat sealed .
When the stand up pouch wholesaler use the coffee bean to decide the capacity between different sizes, such as Impak do in the website. The customer using this methods must make a transformation from the volume of coffee bean to their product. If the volume of coffee bean doesn't equal to the volume they need, it's still hard to find the right pouch size for their products.
Other manufacturers buy the premade stand up pouches to make a trial which add to the cost and time waste. It is hard to find a proper pre-formed pouch for the first time and it is also not simple to make the size adjustment when needed.
Supouch Packaging have rice experience in stand up pouch manufacturing and converting. we have established a proven formula for pouch capacity calculation. As we all know , it is easy to get the overall net volume of the product being packed in the paper box, bottle or block bottom bags, when comparing this volume with the stand up pouch's capacities of different sizes, it is simple to choose the right pouch size. To use this method, all that we need is the net volume of the products to be packed and the intended pouch width. Supouches Packaging is able to offer you a reasonable suggestion of the bottom gusset and height size needed for the template and artwork design.
Let’s take dry food packaging as an example to show the steps of how to choose an exact stand up pouch for your products.
1. We need net volume of the products. You can put your products in a container that the volume can be calculated easily such as rectangular cuboid, a measuring cup or a bottle. Please don’t add the spare volume above in the container when giving us the net volume.
Whatever the shape, size or weight of the inner content such as baking mix, popcorn, dog treat, trail mix , pet food, coconut flour, candies, Snack, nuts, dried fruits, photo chips, cookie dough, pretzels, crunches, fish sticks, or meat balls, the net volume can be achieved in this Way.
For example, we have 4oz salt, 4oz rice, 4oz cereal, let’s see how will the 4oz stand up pouch be different in size specification:
2. You decide the pouch width you prefer for your convenience. Please note that this width is not final because Supouches packaging will give your several related widths depending on your preference to choose from. The width we suggested fit our high-end printing press machine and also is the most economical size for cylinder making. Once the width of stand up pouch is determined, the height and bottom gusset will be generated from our formula. Then the size would be tested by stand up pouch prototyping for your confirmation, finally size adjustment should be made when needed.
3. When the size measurement is at last decided, we will provide the customer with dieline file for artwork design. As we know, this template is indispensible for custom printed stand up pouches if a private label producer want to print their personalized picture onto the pouches.
4. The last point to be noted is the slight difference of bottom gusset. There are three kinds of bottom gusset styles for stand up pouches, the most traditional style is doyen bottom which is elegantly oval sealed, another two are K sealed bottom and corner sealed bottom that is mainly used for liquid and flour packaging.
If you have a requirement for stand up pouch sizing, we are ready to help you find the right size. All you need to give us is a picture of packed contents, the weight ( in gram , lb, ounce, kg, etc.) , its volume (in ml, L or gallon) and the pouch width you prefer. One thing need to be noted is that the width include the side seal width which is about 5-7mm, and the pouch height include zipper’s height, tear notch’s height and top seal. If you need some other features like hang hole, we could add it to the overall height.
As seen from the reference table below, the pouch capacity is limited to a range of not more than and not less than (**)mls because the content’s volume in this range could fit this pouch properly. But it is for customer to decide the final volume of packed contents and the maximum height to which the pouch will be loaded.
Width x Height + Bottom Gusset x 2
Capacity Change from every 10mm in Height
If the capacity shown in the table can't meet your requirement, you are welcome to contact us for size adjustment and pouch prototype.
