Spice packaging bags are composite packaging bags, that is, packaging bags that are not made of a single layer of plastic film, but are laminated by at least two layers of film, at least with a printed outer layer, and inner layer which can direct contact with food,then add a layer of paper or aluminum foiled layer according to the requirements of the protection level.

Two-layer plastic bags

This kind of packaging bag is mainly laminated with an outer printing layer and a food-grade inner layer. According to your needs, it can be made into a glossy surface or a matte surface. The two-layer packaging bag is economical and practical. Generally, a clear window is added to help Consumers can intuitively see what is inside. The clear window can be made into a regular shape or an irregular shape, depending on your personal preference.

Three-layer plastic bags

The three-layer plastic packaging bag consists of a printed outer layer, a food-grade inner layer and a protective aluminum foil layer. The plastic films used in the inner layer are all food-grade plastic films approved by the FDA, which can be in direct contact with food, and the addition of a protective aluminum foil layer can better block oxygen, moisture and ultraviolet rays, and better prevent the oxidation of spices,extend the storage time of spices. However, some customers also like to add a clear window while adding a protective aluminum foil layer. This is also possible. We will add aluminum coating on the side that does not need to be a clear window, and no aluminum foil layer on the clear window side, which is still composed of two layers.

Three-layer paper bags

Some customers like paper bags, which looks more classic and natural. The three-layer paper packaging bag is laminated with printed outer layer, food-grade inner layer and paper layer. The addition of paper is not only beautiful, but also can effectively block oxygen, humidity and UV light. Paper bags can also be added with a clear window, regular and irregular.

Four-layer paper packaging

The four-layer spice bag is generally composed of a printed outer layer, a food-grade inner layer, paper and a protective aluminum foil layer. The protection level is very high, and the price is relatively high.

The bag type can be made into a back-sealed bag or a flat bag. These two bag types are suitable for hanging on the shelf or displayed in a display box. They can also be made into stand up bags, which can stand on the shelf by itself or hang on the shelf. If it needs to be displayed on the shelf, please inform the sales staff in advance that you need to reserve a position for hanging holes, and the top seal should be relatively wider. More delicate spice packaging bags can also choose side gusset bags or flat-bottom bags.

In principle, how many bags can be made from a roll of raw materials, and how much MOQ is. Generally, the length of a roll of raw materials is 3000 meters, mainly calculate how many bags can be out of 3000 meters,that is MOQ.Here’s how to calculate MOQ by different type of bags
