Woven bags play a crucial role in packaging various goods, offering protection and convenience in transportation and storage. One key aspect that distinguishes woven bags is whether they are covered with a film coating or not. Let's delve deeper into the differences between these two types:

Definition of Woven Bag with and without Film Coating

Woven bag film coating refers to the application of a protective layer of film on the surface of the bag to enhance its moisture-proof and waterproof properties. On the other hand, woven bags without film coating lack this additional layer.

Effects on Use:

a. Moisture-proof and Waterproof Performance:

Woven bags with film coating exhibit superior moisture-proof and waterproof performance compared to those without coating. The film layer effectively shields the contents from moisture and water ingress, preserving the quality of the packaged goods.

b. Thickness and Weight:

Generally, film-coated woven bags are thicker and heavier than their non-coated counterparts of the same specifications. This is due to the additional layer of coating, which adds to the overall weight and thickness of the bag.

c. Scope of Use:

Non-coated woven bags are typically suitable for packaging pure dry goods, food items, and chemical fertilizers, where special moisture-proofing isn't required. On the other hand, coated woven bags find their niche in packaging products with higher quality standards, such as cement and minerals, owing to their enhanced moisture-proof and waterproof properties.

Pricing:

The pricing of woven bags with film coating is usually slightly higher than that of non-coated bags of similar specifications, primarily due to the additional cost incurred in applying the waterproof membrane coating.

In conclusion, the choice between woven bags with and without film coating depends on specific packaging requirements and the nature of the goods being transported. While film-coated bags offer superior moisture protection, they come at a slightly higher price point. Understanding these differences enables businesses to make informed decisions regarding packaging solutions, ensuring optimal protection and quality preservation for their products.
