        There are various bags on the market. How to choose the size of the bags and what’s the best capacity of our food products can be packed in these bags? Today we will discuss several common bags.

Sugar food packaging bags

1. Specifications and uses of sugar food packaging bags

        Sugar food packaging bags are generally used to package various fine candies, chocolates, chewing gum and other sugar products, and the choices in the market are becoming more and more diverse. For different sugar, the required packaging bag specifications are also different. The following are the specifications and uses of some of the common sugar food packaging bags:

        18*24cm Ziplock bags: suitable for packaging of meat floss, preserved fruits and other. products, easy to open and seal during use.

2. Packaging bags of different specifications are suitable for different sugar foods

        In addition to the several conventional sugar food packaging bags introduced above, there are also some special forms of sugar products on the market that require corresponding packaging bags. For example, soft candies such as marshmallows need to be packaged in larger bags to prevent them from being squeezed and deformed. For soft candies such as jelly, it is necessary to use cutout zipper bags to ensure taste and quality. At the same time, there are also some packaging bags with moisture-proof, moisture-proof, anti-oxidation and other properties, which can better help sugar manufacturers maintain the fresh taste and quality of their products.

        The specifications of sugar food packaging bags vary depending on the size, weight, and material of the sugar food. Therefore, when purchasing or customizing sugar food packaging bags, you must choose the appropriate specifications and characteristics according to the actual situation. Reasonable packaging bag specifications and materials can help sugar manufacturers better maintain the freshness and quality of sugar products, and increase the brand value and market competitiveness of their products.

Nut packaging bags

        Nuts are common snacks and are often distributed as gifts. The positioning of nuts in the market is closely related to packaging. The right size, material and design are the most important elements during selling the nut products.

the size

        The most common type of nut packaging is plastic bag packaging. Generally, the bag size, thickness, material, bag type, etc. are determined according to the needs of the customers. For example, a five-pound package of nuts requires a 70x110 bag. Generally, there will be some room in a bag, so larger packaging bags are better.

        Different nut brands and different product specifications may have different bag sizes. The size is 15*12cm, which is a relatively common size. The packaging bag size of another 600g nut product is H11 x W12cm, but the packaging bag sizes of different specifications may also be different. For example, for 20g*30 bags, the packaging bag size may be H23 x W13cm. The above information is for reference only, you can choose the appropriate size according to the specific brand and product specifications. Size and capacity design mainly depends on the product style of specific nuts. For example, some pistachio-type nuts are generally packaged in independent small packages according to the customer's choice. Smaller packages are easier to carry.

        Therefore, when manufacturers design snack nuts, they will consider portability, so the packaging capacity will be much smaller. However, small packaging size also has its limitations, that is, more consumables are required, and the loss rate will be higher in terms of production costs. But because of its exquisite features, customers will also pay for it. The specifications of large packaging are generally used for gift packages. If the size is too large or too small in the packaging industry, the loss rate will be greatly increased. Therefore, nut packaging bags generally use a capacity of about 600g and its corresponding size, so the cost can be better controlled.

Coffee bean bags

        First of all, most coffee beans are packaged in 227g/pack. But in addition, there are many other packaging sizes.

        The 227-gram specification is relatively common, mainly due to some historical reasons. Because coffee beans have always been packed in half-pound bags, the equivalent capacity is 227g per bag.

        Of course, many suppliers now set various packaging specifications that meet consumer needs based on their own customer group positioning, such as 500g/pack or 100g/pack, etc.Consumers can choose the amount of coffee beans that suits them according to their own needs.

        When determining the size of the packaging bags, it is still necessary to determine its production cost. The common bag type of 227g is the universal size, which means that most packaging bag manufacturers have existing bag-making molds. Of course, there are also existing bag-making molds for coffee bag sizes of 500g or larger. If existing bag making tools are used, production costs can be greatly reduced. But if it is a bag size that is rare in the market, then special molds must be made, and surely the cost will be double increased.

Potato chip bags

        Normal potato chip packaging bags generally contain 250g, 180g, 90g, 75g, and 30g. Different brands have different standards for the size and dimensions of packaging bags. In normal circumstances, for example, the size of a 250g potato chip bag is W17cm*L 28cm*D 7cm; the size of a 180g potato chip bag is generally 18*25*4cm. Of course, different countries have different sizes of potato chips. Since potato chips need to be crispy, they need to be filled with nitrogen. Normally, half of the reserved bag space is filled with potato chips and half is filled with nitrogen. The purpose is to ensure the crispiness of potato chips. Furthermore, the most important thing is to protect the potato chips from being knocked into pieces and becoming inedible. Therefore, when designing the packaging size of potato chips, it is necessary to consider the volume of nitrogen filled so as to save the size of the packaging bags and save costs.

Pet food bags

        Whether it is a dog food bag or a cat food bag, each small animal's food is different, the particle size is different, and the weight of each package is also different. So first we need to determine the weight and size of the bag.

        Common specifications for pet food packaging include 500 grams, 1.5 kg, 2.5 kg, 5 kg, 10 kg, etc. Small size packaging is ready to be opened and eaten, which is safer and healthier, but the unit price is higher. Therefore, large-sized pet food is currently more popular in the market. However, it is difficult to use up large bags of pet food in a short time after opening, so it involves cat food storage issues. If the pet food is stored improperly, it is prone to problems such as nutrient loss, deterioration, and moisture. Therefore, packaging bags are usually equipped with zippers, which can be opened repeatedly, making it more convenient and hygienic.

        The size and shape of the pet food bag can be designed according to the volume and size of the customer's pet food. From heavy-duty packaging bags of 10kg-15kg, to medium-sized packaging bags such as four-side sealing bags, four-side sealing slider zipper bags, four-side sealing bags, eight-times sealing bags, stand-up bags; and light packaging bags below 500g, three-side sealing bags, sealing bags and stand-up bags can be customized their sizes according to specific circumstances.


        The size of a packaging bag must be based on the characteristics of our own products. Regarding the choice of size, we need to consider the cost perspective. Here we have to think over the materials, the loss rate, and the bag-making mold and so on. This can greatly reduce our costs and increase our profits.
