Single Station Doypack Packing Machine For Granule – TL-PB-300W/500W

Most rotary packaging machines max out at 260-300mm bag widths. When production requirements call for larger formats—5kg rice bags, bulk pet food pouches, club store nut packages—manufacturers discover limited equipment options at reasonable investment levels.

The Soontact TL-PB-300W/500W Single Station Doypack Packing Machine fills the large-format gap. Bag widths extend to 500mm and lengths to 600mm, accommodating the bulk packaging sizes rotary machines cannot handle.

Combined with multihead weigher integration delivering combination weighing accuracy, the TL-PB-300W/500W packages rice, sugar, beans, pet food, and other granules in retail-ready stand-up pouches competing with traditional bags and boxes on warehouse club shelves.

Key Features and Engineering Advantages

( 01 ) Multihead Weigher Precision

Integrated multihead combination weighing delivers accuracy volumetric fillers cannot match on granular products.

The weigher calculates optimal bucket combinations achieving target weights within ±0.5-1.5 grams depending on product characteristics. For bulk packages where target weights reach several kilograms, combination weighing eliminates the systematic overfill causing significant giveaway on high-volume production.

( 02 ) Automatic Dust Removal

Granular products generate dust during filling—fine particles settling on bag openings compromise seal integrity, causing leaks and product contamination.

The built-in dust removal system cleans seal zones before closure, ensuring strong seals maintaining product freshness throughout distribution and storage. The feature proves particularly valuable for dusty products like flour, powdered sugar, and fine grain meals.

( 03 ) Large-Capacity Bag Magazine

The automatic bag feeding magazine holds substantial inventory, reducing operator intervention frequency. Bags load in stacks, automatically advancing to the filling station without manual positioning.

Reduced handling improves production continuity and frees operators for other tasks during extended runs.

Two Models for Different Scale

TL-PB-300W: Mid-Size Versatility

Bag widths from 80-300mm and lengths from 100-430mm cover the range from standard retail portions through medium bulk packages. Production speeds reach 5-15 bags per minute, scaling with bag size and fill weight. The compact 1770x600x1360mm footprint fits production areas where larger equipment cannot operate.

Manufacturers use the TL-PB-300W for 1-3kg rice and grain pouches, medium pet food bags, bulk snack and nut packages, and large seed and garden product pouches. The size range serves retailers seeking premium doypack presentation for everyday staples without committing to maximum bulk formats.

TL-PB-500W: Maximum Capacity

Bag widths from 250-500mm and lengths from 380-600mm accommodate the largest pre-made pouches available. Production speeds of 5-10 bags per minute reflect the time required to fill, settle, and seal high-volume packages properly. The 1880x1140x1450mm footprint supports bulk operations where package size justifies dedicated floor space.

The TL-PB-500W handles 5-10kg rice bags for foodservice and retail distribution, large-format pet food targeting warehouse clubs, bulk commodity packaging for sugar, flour, and beans, and agricultural seed bags serving commercial growers. Operations requiring maximum package capacity find few alternatives matching the TL-PB-500W size range at comparable investment levels.

Applications by Market Channel

( 01 ) Rice and Grain Products

Rice mills and grain packagers serve retail markets demanding premium presentation alongside bulk economy. The TL-PB-300W handles 1-3kg consumer pouches; the TL-PB-500W fills 5-10kg family and foodservice bags.

Stand-up doypacks with clear windows showcase product quality, differentiating premium offerings from commodity sacks.

( 02 ) Pet Food and Animal Feed

Pet food manufacturers face consumer demand for resealable bulk packaging preserving freshness across weeks of feeding.

Dog food, cat food, bird seed, and specialty animal nutrition products package attractively in large-format doypacks featuring zipper reclosure. The multihead weigher ensures consistent fills meeting label claims on high-value premium formulations.

( 03 ) Nuts, Seeds, and Snacks

Bulk nut packaging for warehouse clubs and foodservice distributors requires large-format capability beyond standard rotary machine limits.

Almonds, cashews, mixed nuts, trail mixes, and seed blends fill accurately despite irregular piece sizes, with combination weighing optimizing each package regardless of individual piece weight variation.

Frequently Asked Questions

( 01 ) How does single-station speed compare to rotary machines?

Single-station machines operate at 5-15 bags per minute versus 30-55 bags per minute on rotary systems. However, bulk packages containing 3-10kg per bag often produce equivalent or greater hourly output by weight.

A single-station machine filling 10 bags per minute at 5kg each produces 3,000kg per hour—matching or exceeding rotary machines filling smaller portions at higher cycle rates.

( 02 ) Can the machine handle both small and large bags?

The TL-PB-300W spans 80-300mm widths, covering standard retail through medium bulk sizes on one machine.

Operations requiring both small portions and maximum bulk sizes may benefit from pairing the TL-PB-300W for smaller formats with the TL-PB-500W for largest packages, or selecting the TL-PB-300W for versatility across the mid-range.

( 03 ) Is nitrogen flushing available for freshness extension?

Yes, optional nitrogen flushing displaces oxygen before sealing, extending shelf life for products sensitive to oxidation.

Nitrogen flushing proves particularly valuable for nuts, seeds, and other products where rancidity limits storage duration.
