Choosing containers made from more sustainable materials is a key step in reducing the environmental impact. Several alternatives offer reduced environmental footprints compared to traditional plastics.

Glass: Glass containers are durable, reusable, and made from readily available materials like sand. They are fully recyclable and do not leach chemicals into food. However, they are heavier and more prone to breakage than plastic.
Stainless Steel: Stainless steel containers are another durable and reusable option. They are resistant to staining and odors, and are also recyclable. However, they can be more expensive than plastic or glass.
Plant-Based Plastics (Bioplastics): Some snap lock containers are made from bioplastics, such as polylactic acid (PLA), derived from renewable resources like cornstarch or sugarcane. While often compostable, the conditions required for composting can be specific, and many bioplastics still end up in landfills.
Silicone: Food-grade silicone containers are flexible, durable, and heat-resistant. They are generally considered safe for food contact and can be recycled, though recycling options for silicone can be limited.

Purchasing Guide and Tips

Choosing the right snap lock food storage containers can seem overwhelming given the variety available. This guide provides essential considerations to help you make informed decisions, ensuring you select containers that meet your needs and budget. Understanding these factors will enhance your food storage experience.

Factors to Consider Before Buying

Before purchasing, several aspects need careful evaluation. These factors influence the containers’ suitability for your specific requirements and long-term usability.

Material: Consider the material’s properties. Plastic containers, like those made from polypropylene (PP) or polyethylene (PE), are generally lightweight and affordable, but may stain or retain odors. Glass containers, such as those made from borosilicate glass, offer excellent clarity, durability, and are often oven-safe, but they can be heavier and more prone to breakage if dropped. Stainless steel options are durable, rust-resistant, and suitable for various foods.
Seal Integrity: Evaluate the seal’s effectiveness. Look for containers with a tight, airtight seal, preventing leaks and preserving food freshness. Ensure the snap locks are secure and easy to operate. A good seal is crucial for preventing spills and maintaining food quality.
Size and Capacity: Assess your storage needs. Consider the size and capacity of the containers based on the typical portions you prepare and store. Choose a range of sizes to accommodate various foods and leftovers.
Shape and Design: Consider the shape and design for efficient storage. Rectangular or square containers often maximize space utilization in the refrigerator and pantry. Stackable designs save space and improve organization.
Ease of Cleaning: Determine cleaning convenience. Opt for containers that are dishwasher-safe for easy cleaning. Ensure the material is resistant to staining and odors. Consider the lid design for ease of cleaning, avoiding complex grooves that might trap food particles.
Durability: Evaluate the container’s longevity. Check the material’s durability, impact resistance, and resistance to temperature fluctuations. Choose containers that can withstand regular use and washing without warping or cracking.
BPA-Free Certification: Prioritize safety by choosing BPA-free containers. This certification ensures the containers do not leach harmful chemicals into your food.
