How to Choose the Right Packaging Film for Milk Powder?

Recognizing the Preservation Challenges for Milk Powder  

Like milk, milk powder is also susceptible to moisture, oxygen, and light exposure. When milk powder is gone clumped, bad, or lost nutritional value, packaging needs to address these challenges. When packaging film is selected, the first priority is to prevent moisture ingress.  Milk powder clumping is a problem caused primarily by moisture ingress. Packaging must also reduced oxygen ingress, since the powder is degraded with time if oxygen is present. Milk powder also needs protection from harmful light, particularly UV light, which helps to preserve the powder and prolong its shelf life.

Prioritizing Safe Packaging Compliance  

The packaging for milk powder, which can be consumed by all ages, especially children, must adhere to the highest safety practices. The packaging film must comply with the most stringent safety food grade protocols. The film must comply with regulations like the FDA 21CFR 177.1520, a standard that food protective packaging can be 177.1520, a standard that food protective packaging can harmlessly used for food. Do not use packaging materials that have BPA or any toxic film These materials are hazardous in exceeding powdered milk.  the safety certificate.

Analyze the Barrier Performance of Various Film Materials

The barriers provided by different packaging film materials affect the degree of protection given to milk powder. The materials may be polypropylene (PP), polyethylene (PE), or even composite films that consist of several layers. While films made of PE do well at stopping moisture, they also let oxygen pass through. With respect to oxygen permeability, films made of polypropylene do not provide adequate protection, even though they are preferable when it comes to heat resistance during processing. Composite films, whether they are layered with PE, PP, or even aluminum foil, provide the best overall protection. The rest of the packaging materials do not provide adequate protection, as they do not simultaneously block moisture, oxygen, and light. That's why composite films are the best packaging materials for milk powder becuase they block moisture, oxygen, and light simultaneously.

Think About Seal Integrity and Ease of Use  

No matter how efficient your packaging film barrier properties are, poor integrity would render it ineffective. Sealability, in the case of film packaging, means whether it can be sealed tightly or would need workarounds like heat sealing. As packaging films are barriers to moisture and oxygen, they should be promptly sealed and tightly, or else any gaps would undo the efforts on barrier properties. From the consumer perspective, ease of use would be the first thing they consider. Resealable zippers are a benefit in many cases. They allow consumers to open a container, take out a specified amount of something like milk powder, and seal it again to keep the remaining product powder fresh.

Think About Branding and Sustainable Practices  

Beyond protection and safety, there are branding and sustainability aspects as well. With film packaging, brand statements become visible and important. With the ability to custom print in high quality, brands can value add to packaging films by advertising the product’s nutritional values, expiration date, and brand logo which can help instill consumer trust. Besides, sustainability is a major player now in consumer packaging. Adopting recyclable films or nesting your materials would help cut the use of packaging materials. Minimizing thickness of packaging films is a good first step in sustainability.
