When you are desired to seal your products, you might go for the zipper bags. And now there are many kinds of zipper bags on the market. How should you choose the right one for your products? Consider the following factors to make it easier to find the perfect bag among the dizzying array of zipper bags.
What to consider when selecting the ziplock bags
First of all, we consider the material of the bags but also consider other factors such as reusability, size and capacity, thickness, sealing design, etc.
Material
There are all sorts of zipper bags, such as leather zipper bags, plastic zipper bags, canvas zipper bags, and paper zipper bags. However, manufacturers generally use plastic and paper zipper bags to pack their products. So let’s focus on the materials of these two bags.
With the development of science and technology, more and more resources can be used for the production of plastic bags. Among them, the raw materials of traditional plastic bags are from non-renewable resources such as oil, and the raw materials of traditional plastic are toxic. It is not safe to pack or store some items. However, the advent of biodegradable and compostable plastic bags has greatly reduced the safety risks, thus reducing the concerns of manufacturers. Biodegradable and compostable bags, made of corn starch or cellulose, can break down into carbon dioxide, water, and other biomass under certain conditions over time. By contrast, it is recommended that you use biodegradable and compostable ziplock bags for your products.
Paper zipper bags are made from virgin pulp that is not bleached or from recycled paper – used reprocessed paper. Now more and more bags contain a waterproof layer outside and an anti-oil greaseproof layer inside so that they are more suitable to pack and store food.
Generally speaking, the raw material determines the bags’ final texture, smell, and load capacity. Therefore, it is very important for you to choose the right material.
Reusability
Single-use zipper bags should be thrown away after use, which is not eco-friendly. Selecting reusable zipper bags can reduce your expenses and contribute to the environment. For customers, they will prefer these reusable bags in daily life. If a bag is initially used to hold fruit, it can also be used to store vegetables in the refrigerator. No more wasted new bags.
Sizes and capacity
There are a large number of zipper bags in customizable sizes for us to choose from. Small-size bags are used to store small objects and medium-size and large-size bags are used to store food or clothes. Choose the sizes you want, you must measure and determine the width, length, and height of your content. Then measure the length from the bottom to the top and the width from side to side. When designing, it is necessary to ensure that the bag is larger than the precise item, so that the item can be easier to fit into and take out of the bag.
Thickness
Plastic bag thickness is expressed in the mic. 40-mic zipper bags are the most common thickness and satisfy most applications. If you want thicker ones for heavy items, the materials involved in the production are critical. Made of starch and biodegradable raw materials, biodegradable and compostable plastic bags are more strong and durable than traditional plastic bags. Therefore, they are becoming more and more popular all over the world.
Sealing design
Good seal depends on the closing mechanism of the bags. Single zippers and double-press zippers are the most common styles. Relatively speaking, double-press zipper bags have better sealing but at the same time, they are more expensive. If your products need more sealed packaging, a double-press zipper will be more suitable. Certainly, single-zipper bags can meet the packaging or storage of most products. And they are also more economical for businesses or individuals.
In addition to the above considerations, we might also consider storage space and toughness, durability, etc. Which factor is most important depends on the characteristics of your product and the features you want.
Conclusion
Considering the above factors, I believe you can find the right ziplock bags for your heart. Combining the above factors, biodegradable and compostable zipper bags are the ideal alternative for you. But their raw materials are more expensive and need more technical support, so we must spend more money on them. So choose the right zipper bags based on your financial ability, and then consider the properties of the bags and the impact on the environment.
