How to Choose the Right Sachet Size and Material for Your Packing Machine

Sachets are a versatile and cost-effective packaging solution for a wide range of products. They are ideal for small, single-serve items such as coffee, tea, spices, and snacks. Sachets can be made from a variety of materials, including paper, plastic, and foil. The size and material of the sachet will depend on the product being packaged and the desired shelf life.

When choosing the right sachet size, it is important to consider the following factors:

Product size and shape

The size of the sachet should be slightly larger than the product to ensure a snug fit. The shape of the sachet should also be compatible with the product. For example, a rectangular sachet is ideal for flat products, while a round sachet is ideal for round products.

Product weight

The weight of the product will determine the thickness of the sachet material. Heavier products require thicker sachets to prevent tearing or bursting.

Desired shelf life

The shelf life of the product will determine the type of material used for the sachet. Paper sachets are ideal for products with a short shelf life, while plastic or foil sachets are ideal for products with a longer shelf life.

When choosing the right sachet material, it is important to consider the following factors:

Product compatibility

The material of the sachet should be compatible with the product being packaged. For example, paper sachets are not suitable for oily products, as they will absorb the oil and become soggy.

Barrier properties

The material of the sachet should have the necessary barrier properties to protect the product from moisture, oxygen, and light. For example, foil sachets are ideal for products that are sensitive to moisture, while plastic sachets are ideal for products that are sensitive to oxygen.

Cost

The cost of the sachet material is an important factor to consider. Paper sachets are typically the most cost-effective option, while plastic and foil sachets are more expensive.

In addition to the size and material of the sachet, it is also important to consider the type of packing machine that will be used. Different packing machines require different types of sachets. For example, vertical form fill seal (VFFS) machines require pre-formed sachets, while horizontal form fill seal (HFFS) machines can form and fill sachets from a roll of material.

By following these guidelines, you can choose the right sachet size and material for your packing machine and ensure that your products are packaged safely and efficiently.
