Wholesale Crimpable Rim 4.37"x3.29" 4oz/120ml Aluminum Foil Container for Sauce Portion & Dry Side Dish

This 4.37" by 3.29" silver foil tray holds approximately 4oz or 120ml, making it a practical choice for single serve condiments or small side dishes. The tray is made from foodgrade aluminum with a crimpable rim, which allows you to fold the edge over a lid for a secure closure. It is not designed for soups or watery foods, but works perfectly for sauces, dressings, butter, dips, rice, coleslaw, or fruit portions. The rectangular shape and shallow depth help it stack efficiently in delivery bags or refrigerated storage, saving space for both restaurants and home users.

Aluminum foil containers have become a staple in the food packaging industry, especially for takeout and catering. The global market for foil trays continues to grow, driven by the rise of food delivery apps and the shift away from single use plastics. Small formats like this 4oz tray are particularly popular for portion control in healthy meal plans, ghost kitchens, and food trucks. From a production perspective, high speed automatic presses can produce 40 to 80 pieces per minute, depending on the size and complexity. China supplies more than half of the world's foil containers, with major manufacturing hubs in Guangdong, Zhejiang, and Jiangsu. Factories there offer fully automated lines, custom tooling, and various surface finishes – from smooth walls to wrinkled designs for extra rigidity.

One of the key advantages of aluminum is its recyclability. Used foil trays can be cleaned and melted down to make new products without losing quality. Recycling aluminum uses about 95% less energy than producing primary aluminum, which significantly reduces carbon emissions. Many municipalities accept clean foil trays in their recycling programs, making it easier for end consumers to dispose of them responsibly. For B2B buyers, sourcing from a factory with FDA or EU food contact certification ensures compliance with international safety standards. 

This 4.37"x3.29" tray can be paired with a cardboard or foil lid, and the crimpable rim allows fast manual folding – no heat sealing equipment required. It is also oven and freezer safe, so leftovers can be reheated directly in the tray or stored for later use. For restaurants and meal prep services, using recyclable aluminum trays instead of plastic can improve brand image and appeal to ecoconscious customers.

Whether you need this size for sauce portions, side dishes, or sample tasting events, the tray offers a balance of compact dimensions and practical depth. It is light enough to reduce shipping costs yet sturdy enough to protect its contents during delivery.
