On high-output monolayer T-shirt sack lines equipped with 65–90 mm single-screw extruders at 24:1–30:1 L/D, internal bubble cooling, and dual-lip air rings, DGDX-6095H is processed at a nominal melt flow rate of 0.90 g/10 min at 190°C/2.16 kg per ASTM D1238-20 and nominal density 0.960 g/cm³ per ASTM D1505-18. The resin is supplied as virgin pellets and is either run at 100 wt% or as 70–85 wt% DGDX-6095H with 15–30 wt% butene-based LLDPE at density 0.918–0.920 g/cm³ and MI 1.0 g/10 min added to increase transverse-direction Elmendorf tear and dart impact. Drying is not routinely required below 60% RH; when silo transit condensation or high ambient humidity exceeds 60% RH, hopper drying at 80°C for 2 h prevents surface pitting. At die gaps of 1.8–2.2 mm and BUR 3.0:1–4.0:1, the melt temperature window is held at 205–215°C at the die; barrel set points below 180°C are avoided because screw amperage rises and melt fracture appears on shallow-gap film lines. Production lines typically run at 120–160 kg/h depending on die diameter, with bubble stability controlled by internal bubble cooling and frost-line height set between 5 and 8 die diameters.

The terminal product is T-shirt grocery sack film at 0.020–0.035 mm thickness, converted on hot-knife or impulse-seal bag machines. Compliance for retail carriers in dry-food contact is evaluated under FDA 21 CFR 177.1520(c) for olefin polymers and, for EU shipments, under Regulation (EU) No 10/2011, with overall migration not exceeding 10 mg/dm² when tested according to EN 1186-1:2002. In non-food carrier applications, EU Directive 94/62/EC heavy-metal restrictions apply.

When downgauging refuse sacks to 0.015 mm does orientational tear balance require LLDPE modification?

Commercial refuse bag converting lines use DGDX-6095H in mono-layer and three-layer annular die formats with die gaps from 1.4–2.0 mm. For a 0.015 mm target gauge, machine-direction tear values of virgin DGDX-6095H often fall below the threshold required by institutional can liners when the tubular bubble is collapsed at high haul-off speeds; therefore converters blend 20–30 wt% of a C6 or C8 linear low density polyethylene at nominal density 0.920 g/cm³ and MI 1.0 g/10 min, leaving DGDX-6095H at 68–80 wt%, with 0–2 wt% of a fluoropolymer processing aid masterbatch to control melt fracture and die-lip build-up. The production line configuration for refuse sacks usually includes a grooved-feed extruder with screw diameter 60–90 mm and L/D 28:1–33:1, an internal bubble cooling stack, and automatic gauge control. Blow-up ratio is held at 2.8:1–3.2:1 with frost-line height set between 6 and 10 die diameters to stabilize the bubble. Melt temperature at the die is maintained at 200–210°C.

Compliance standards for this stream include REACH (EC) No 1907/2006 Article 33 for SVHC communication above 0.1 wt%, and EU Directive 94/62/EC on packaging and packaging waste, where the sum of lead, cadmium, mercury and hexavalent chromium in packaging materials is limited to ≤ 100 ppm. The terminal products are refuse sacks, roll-off container liners, and institutional can liners, with film thicknesses from 0.015 mm to 0.035 mm.

Dry food and cereal liner film extrusion with DGDX-6095H is performed on 45–75 mm extruders with polished screws and nitrided barrels, using either 100 wt% virgin DGDX-6095H or a blend of 85–95 wt% DGDX-6095H and 5–15 wt% food-grade LDPE at density 0.924 g/cm³ and MI 0.25 g/10 min to improve heat-seal initiation at lower jaw temperatures. The film is manufactured at 0.025–0.035 mm thickness with BUR 2.5:1–3.5:1 and die gap 1.6–2.0 mm. Melt temperature at the die is typically 205–215°C, and the bubble is internally cooled to reduce blocking on high-speed slitting lines. Food-contact compliance is demonstrated under FDA 21 CFR 177.1520(c) for olefin polymers and Regulation (EU) No 10/2011, including the specific migration limits for any additives under Annex II; the final formulation must be tested in simulant E for long-term dry contact and total migration per EN 1186-1:2002. End product types are cereal liners, cracker wrappers, powdered beverage internal liners, and dry food pouches.

What thermal and output limits govern 0.012 mm overwrap film extrusion of DGDX-6095H?

Ultra-thin overwrap film lines running DGDX-6095H are typically equipped with 40–60 mm extruders with barrier screws, downstream high-speed haul-off, and corona treatment units. At 0.012 mm the material is less often processed neat because low melt temperature causes shark-skin melt fracture on polished dies; operators maintain melt temperature at 210–218°C and either add 0.5–1.0 wt% of fluoropolymer processing aid masterbatch to otherwise neat DGDX-6095H, or dilute DGDX-6095H to 90 wt% with 10 wt% high-pressure LDPE to delay crystal melt fracture. The die gap is reduced to 1.0–1.4 mm, BUR is set at 3.0:1–4.0:1, and the frost-line is lowered to 3–6 die diameters to preserve optical quality. Downstream, the film is often corona-treated to 38–42 mN/m surface energy for print adhesion. Compliance for non-food secondary packaging references EU Directive 94/62/EC heavy metals and REACH (EC) No 1907/2006, with CONEG model legislation applied in North America. The end products are thin protective overwraps, magazine mailing wraps, and industrial garment bags.

In three-layer heavy-duty shipping sack lines using 3 × 70 mm extruders at L/D 30:1, DGDX-6095H constitutes the heat-seal and outer skins while a recycled HDPE core is introduced at 20–30 wt% of the total structure; the remaining 70–80 wt% is DGDX-6095H distributed between skin layers. Extrusion uses internal bubble cooling with a die gap of 1.8–2.4 mm, BUR 2.2:1–2.8:1, and melt temperature 195–210°C. The higher gauge film, typically 0.060–0.100 mm, passes through a collapsing frame and is surface-treated to improve adhesion for flexographic printing. Batch-to-batch MFI drift in the recycled core above 0.3 g/10 min widens gauge variation and narrows the heat-seal window because skin and core layer viscosity mismatch reduces interface stability. Compliance is assessed under EU Directive 94/62/EC heavy metal limits and REACH (EC) No 1907/2006 Article 33, with ISO 18601:2013 referenced by packagers evaluating reuse and material recovery. Terminal products are heavy-duty shipping sacks, construction debris bags, and bulk bag liners.
