Plastic buckets are ideal for storing protein powders because they are air-tight, water-tight and light-proof, protecting and extending the shelf-life of your product. They are tamper-evident for secure shipping and storage, and have rim-lock lids for convenient opening and closing.

Protein powders typically last 1 to 2 years from the manufacturing date. Once opened, they should be used within 3 to 6 months. Protein powders should be stored in air-tight containers with close-fitting lids to prevent spoilage.

Protein, whey and creatine powders can be spoiled if they are not stored correctly. Signs of spoliation include a rancid smell, clumping or a bitter taste. If this happens, the powder should be discarded regardless of the use-by date.

Plastic screw top jars are popular for nutrition supplements because they are light, cost-effective and unbreakable. Glass jars are ideal for high-value products, and many customers prefer glass packaging. Glass also recycles forever, making it a more sustainable option.

IML printing is available on our tubs and buckets. This printing technique happens, "in the mould" and is part of the production process, resulting in a professional and highly durable finish. We also offer an adhesive label service, which works well for lower volume runs and limited edition products.
