1. Plastic Shopping Baskets: Lightweight and Inexpensive, but Environmentally Controversial
Plastic is the most common material for shopping baskets in supermarkets and convenience stores, accounting for about 70% (Source: 2022 Global Retail Packaging Report). There are three main types:
PP (Polypropylene): High hardness, impact-resistant, can bear up to 15kg, cost approximately 3-8 yuan per basket, but is non-biodegradable.
PE (Polyethylene): Good flexibility, suitable for folding designs, but easily deformed and yellows with long-term use.
Recycled Plastics: Improved environmental friendliness, but strength reduced by 30%, mostly used for promotional gifts.
2. Metal Shopping Baskets: Durable but Bulky
Stainless Steel: Highly rust-resistant, can bear over 50kg, commonly found in warehouse-style supermarkets (such as Costco), priced at 20-50 yuan per basket.
Electroplated Iron Wire: Chrome-plated surface for scratch resistance, but prone to rust in humid environments, weighing 1.5-2kg, inconvenient to handle.
Advantages: Service life can reach over 10 years, suitable for high-frequency commercial scenarios.
3. Natural Materials: Environmental Protection and Limitations
Rattan/Bamboo: Breathable, suitable for farmers' markets, but susceptible to water damage and mold; price: 15-30 RMB per unit.
Non-woven Fabric: Foldable and lightweight (only 200g), but can only support about 5kg; primarily used for environmental awareness campaigns.
Data Comparison: Rattan basket production has 60% lower carbon emissions than plastic (Source: 2021 "Green Packaging Research"), but its market share is less than 5%.
4. Emerging Materials: Bio-based and Biodegradable Trends
PLA (Polylactic Acid): Extracted from corn starch, biodegrades naturally in 180 days, but costs three times more than plastic.
Sugarcane Fiber: Compressive strength close to PP plastic; piloted on Amazon; price: approximately $12 per unit.
Purchase Recommendations:
For commercial use, prioritize metal or thick-walled PP plastic.
For short-term household use, consider non-woven fabric.
For strong environmental protection needs, PLA or rattan are highly recommended.
