How to choose flour packaging bags? Which is better: kraft paper flour bags or composite flour bags?

When it comes to flour packaging, both kraft paper flour bags and composite flour bags have their own advantages. Guangdong Guowei Guanli New Materials Co., Ltd., as a professional provider of “paper-based alternatives to plastic” solutions, offers sustainable packaging products that provide an environmentally friendly option for the industry.

 

When selecting flour packaging bags, key considerations include sealing performance, moisture resistance, environmental friendliness, and cost. Poor sealing can lead to flour becoming damp and clumping, environmental friendliness relates to the environmental impact after packaging disposal, and cost is a key consideration for long-term procurement by businesses.

Kraft paper flour bags are Food Packaging Paper Bags made from high-strength kraft paper, with some undergoing lamination treatment to enhance moisture resistance. As a biodegradable packaging product, it is made from natural materials and can be decomposed after disposal, aligning with the trend toward environmentally friendly packaging. They have moderate breathability, preventing flour from spoiling due to heat and humidity, and feature simple printing, making them suitable for flour brands emphasizing natural and healthy attributes. However, pure kraft paper bags have slightly inferior moisture resistance compared to composite bags and are more suitable for short-term storage or use in dry regions.

 

Composite flour bags are made from materials such as plastic film, offering strong moisture resistance and excellent sealing properties, thereby extending the shelf life of flour. However, most composite bags are not biodegradable, do not align with environmental trends, and their costs fluctuate significantly with raw material prices.

 

From an application perspective, for small-scale household flour packaging, kraft paper flour bags, as a type of paper bag packaging, are lightweight and environmentally friendly, enhancing a brand's green image; for industrial bulk packaging with long storage periods, composite bags offer superior moisture resistance, but come with higher environmental costs.

 

Guangdong Guowei Guanli's kraft paper flour bags have significantly improved moisture resistance through process optimization, with some products rivaling composite bags in performance while maintaining cost advantages, making them a preferred choice for many companies. For businesses pursuing “carbon reduction and environmental protection + practical durability,” kraft paper flour bags are undoubtedly a more aligned choice with sustainable packaging principles, particularly suitable for use as courier packing bags in e-commerce channels, fully implementing a green packaging supply chain.
