LK Packaging P10F1209+4BGLTC Clear Poly Flat Bags with Bottom Gusset and Long Tie Closure
The LK Packaging P10F1209+4BGLTC is a 1.0 mil clear polyethylene flat bag measuring 12″ x 9″ with a 4″ bottom gusset and a long tie closure (LTC) neck extension. The LTC feature adds extra material above the fill line, providing ample length for tying, twisting, or sealing the bag securely after filling without the bag neck slipping from the closure. This format is especially valued in high-speed bakery and produce packing environments where closure speed and reliability are critical.
What Is a Long Tie Closure on a Poly Bag?
A long tie closure (LTC) is an extended neck section above the main bag opening designed to facilitate faster and more secure manual or machine tying. The extra material gives operators more to grip when applying twist ties, rubber bands, or heat seals, reducing fumbling and closure failures on fast-moving production lines. For high-volume bakery operations that pack hundreds of bags per hour, the LTC feature pays for itself in labor efficiency and reduced waste from poorly sealed bags.
Dimensions and Capacity of the P10F1209+4BGLTC
At 12″ wide and 9″ tall with a 4″ expanding bottom gusset, this bag is configured for wide, relatively compact products that benefit from a broad, stable base. Flat bread, focaccia, pizza rounds, and wide pastry products fit naturally into the wide 12″ opening. The expanded gusset creates a broad, flat bottom that keeps round or wide items stable during transport and display without rolling or shifting inside the bag.
Food Service Applications for Wide-Format Gusset Bags
Pizzerias packaging take-and-bake pizza rounds, bakeries packaging flatbreads and focaccia loaves, and grocery delis packaging wide cheese rounds all benefit from the 12″ wide format. The combination of the wide opening and LTC extension enables rapid hand-packing of large, flat items on busy production lines. Commissary operations producing large quantities of flatbread products standardize on this format for its efficiency advantages over standard bags in the same general size category.
Why LK Packaging for Specialty Closure Poly Bags?
LK Packaging produces specialty closure poly bags like the P10F1209+4BGLTC with precise neck length tolerances to ensure consistent LTC performance across the full case. Bags with inconsistent neck lengths create closure problems on production lines, forcing operator intervention and slowing throughput. The consistent LTC geometry from LK Packaging ensures automated and manual closure equipment performs reliably without adjustment, maintaining production speed and packaging quality.
High-Volume Ordering for Bakery and Food Production
LK Packaging supplies the P10F1209+4BGLTC in bulk case quantities suited to high-volume bakery, commissary, and specialty food production operations. The FDA-compliant LDPE film is safe for direct food contact, and the consistent 1.0 mil gauge ensures the bag handles well on both manual and automated packaging lines. Businesses with regular poly bag needs benefit from LK Packaging’s reliable supply chain and competitive bulk pricing.

What great and speedy service. Web site easy to use, responses from site at purchase and shipping clear and timely. Our purchase was a rather small (5,000 bags) for a market test but the prices we received for this modest purchase and shipping were great value.
