LK Packaging KF0304ST Kwik-Fill® Pre-Opened Bag 3″ x 4″ Standard 1.4 Mil LLDPE | Automatic Packaging

LK Packaging KF0304ST Kwik-Fill® Pre-Opened Bags — 3″ x 4″, 1.4 Mil Standard LLDPE for Automatic Packaging

The LK Packaging KF0304ST is a 3″ x 4″ standard-duty Kwik-Fill® pre-opened bag on a roll for automated packaging equipment. At 1.4 mil LLDPE, the KF0304ST provides economical high-volume bagging performance for lightweight, smooth-surface items in the versatile 3″ x 4″ format. Ideal for accessories, light apparel components, small food portions, and other non-sharp contents that benefit from a longer bag profile than the 3″ x 3″ format.

When Does a 3″ x 4″ Standard Bag Make More Sense Than a 3″ x 3″?

The KF0304ST’s additional 4″ length is beneficial when products are taller than comfortably fits in a 3″ bag, or when additional headspace above the product is needed for clean heat-sealing without compressing contents against the seal. Longer accessories, folded garments, portion packs with multiple pieces, and items requiring a header or label area above the product all benefit from the 3″ x 4″ format.

Why Is LLDPE Preferred Over LDPE for Standard-Duty Auto-Bag Applications?

LLDPE provides better impact resistance and drop performance than LDPE at 1.4 mil, maintaining bag integrity through filling, sealing, and conveyor transport better than standard LDPE at equivalent thickness. For high-speed automated packaging lines where bags experience mechanical impact from filling heads and conveyor transitions, LLDPE’s toughness reduces bag failure rates and waste.

E-Commerce Fulfillment Centers Use KF0304ST for Lightweight Accessory Auto-Bagging in Custom Kit Assembly

E-commerce fulfillment operations and subscription box packagers assembling custom kits with small accessory add-ons — buttons, patches, care cards, and small branded items — rely on standard-gauge pre-opened bags like the LK Packaging KF0304ST to automatically bag accessory components at kit-assembly line speeds. The 3″ x 4″ format fits folded cards, small garment accessories, and lightweight branded items, keeping kit assembly lines moving at high throughput without manual bag handling.
