LK Packaging KF02545MD Kwik-Fill® Pre-Opened Bag 2-1/2″ x 4-1/2″ Medium Duty 1.9 Mil LDPE | Automatic Packaging

LK Packaging KF02545MD Kwik-Fill® Pre-Opened Bags — 2-1/2″ x 4-1/2″, 1.9 Mil Medium Duty LDPE for Automatic Packaging

The LK Packaging KF02545MD is a 2-1/2″ x 4-1/2″ medium-duty pre-opened bag on a roll for automatic packaging equipment. At 1.9 mil LDPE, these Kwik-Fill® bags bridge the gap between standard-duty economy bags and heavy-duty LLDPE options — providing enhanced puncture resistance for moderately abrasive contents while maintaining good clarity and seal performance on automated bagging lines. The wider 2.5″ format accommodates products too wide for 2″ bags without stepping up to a 3″-wide roll configuration.

What Products Are Best Suited for the 2-1/2″ x 4-1/2″ Kwik-Fill® Format?

The KF02545MD’s 2.5″ x 4.5″ dimensions are well-suited for products that are slightly wider than 2″ standard bags can accommodate — including medium-size hardware kits, blister-card supplements, snack packs, pharmaceutical sample packets, and accessories like multi-piece keychain sets or small cosmetics that need both the width and length of this format to lay flat in the bag without folding.

Why Choose Medium Duty 1.9 Mil LDPE for Automatic Bag Lines?

Medium-duty 1.9 mil LDPE provides balanced performance for contents that are too abrasive for 1.4 mil standard bags but don’t require the maximum puncture resistance of 2.8 mil LLDPE. This gauge is commonly used for hardware samples, mixed small parts, and food products with harder textures where moderate puncture risk exists. LDPE also offers better clarity than LLDPE at equivalent gauges, which can be important for retail-display bagging applications.

Pharmaceutical Sample Distribution Lines Use KF02545MD for Unit-Dose and Sample Packet Auto-Bagging

Pharmaceutical manufacturers and contract packagers running automated unit-dose and sample distribution packaging lines rely on the LK Packaging KF02545MD’s medium-duty construction and wider format to handle blister card overflow portions, sample sachets, and multi-tablet packet assemblies that are too wide for standard 2″ auto-bag rolls. The 1.9 mil LDPE provides sufficient barrier and bag integrity for pharmaceutical packaging environments without the cost of heavy-duty film.

How Do I Know If My Equipment Supports 2-1/2″ Wide Kwik-Fill® Rolls?

Kwik-Fill® pre-opened bags must match your packaging machine’s roll width specification. Verify your equipment’s supported bag widths before ordering — most pre-open bag systems are configurable for multiple roll widths, but confirm with your equipment supplier or contact NFCbags.com for guidance on matching the KF02545MD to compatible automatic packaging equipment.
