105mm Tinplate Base Ends | Food-Grade Bottom Lids for Instant Soy Milk Powder Packaging

2026-07-20

Professional Protection for Soy Milk Powder Storage

Instant soy milk powder is highly susceptible to quality degradation from moisture, oxygen and external contaminants. Fine powder particles easily clump, lose solubility, and develop stale flavors once exposed to humid air during production, transportation or long-term shelf storage. Unlike ordinary packaging bases, our 105mm tinplate base ends feature a precision crimped sealing structure that forms a tight protective barrier, effectively blocking ambient moisture and air infiltration. This stable sealed environment prevents powder caking, maintains fine powder texture and original bean flavor, and preserves the full nutritional value of plant-based soy protein.

Adopting premium food-grade inner coating, these base ends avoid powder adhesion and residue buildup, ensuring clean filling and smooth can sealing during automated production. The safe non-toxic lining is fully compatible with dry nutritional powder formulas, with no harmful substance precipitation, complying with international food contact safety standards for long-term product storage.

Structural & Production Advantages

Featuring strict dimensional consistency, the 105mm standard caliber ensures seamless matching with supporting can bodies, adapting perfectly to high-speed automatic seaming lines. It effectively reduces assembly errors, powder leakage and defective rates during mass production, greatly boosting overall packaging efficiency for food factories.

The thickened tinplate structure delivers outstanding compression and stacking resistance. It withstands heavy pallet stacking and bumpy long-distance shipping, preventing base deformation, cracking and powder leakage—common issues in cross-border logistics. The flat, smooth base design also keeps finished cans stable during shelf display and warehouse storage, optimizing retail presentation and inventory management.

Versatile Application Scope

Primarily optimized for instant soy milk powder packaging, these 105mm tinplate base ends fit a wide range of plant-based nutritional powder products. They work excellently for black bean powder, multi-grain powder, oat powder and other healthy brewed powder items. Suitable for family-sized daily packaging, retail canned products and bulk export orders, these universal base lids meet diverse packaging needs for health food brands and processing enterprises.
