Philippine 1kg Laundry Powder Premade Four-Side Seal Bag Packing Machine

This is a customized 1kg laundry powder premade four-side seal bag packing machine application case for a Philippine customer.

The customer needed an automatic packing solution for laundry powder / washing powder / detergent powder, mainly for 1kg and 2kg premade four-side seal bags. According to the production order, the machine was configured with a 4-head weigher, Siemens control system, and components suitable for stable detergent powder packaging.

Unlike roll-film packaging machines, this project uses premade four-side seal bags. The machine completes automatic bag feeding, bag opening, weighing, filling, sealing, and finished bag output. This solution is suitable for detergent powder factories or local contract packing companies in the Philippines that need flexible packaging for medium and large-size powder bags.

Bag Size Requirement

Packing WeightBag Size
1kg230 × 310 mm
2kg270 × 350 mm

The project is mainly focused on 1kg laundry powder premade bags, while the machine also considers the customer’s 2kg detergent powder bag requirement.


Why This Philippine Customer Chose Premade Four-Side Seal Bags

For 1kg and 2kg detergent powder packaging, premade four-side seal bags are suitable when the customer already has printed bags or wants a cleaner retail package appearance.

1. Suitable for local detergent powder retail packaging

In the Philippines and other Southeast Asian markets, detergent powder is commonly sold in different bag sizes. For 1kg and 2kg products, the package needs to look clean, strong, and suitable for shelf display.

2. Better flexibility for different bag sizes

Premade bag packaging is practical when the customer needs to switch between different weights, bag designs, or product types. This is useful for detergent powder factories and co-packers that handle multiple SKUs.

3. Stronger packaging appearance

Four-side seal premade bags provide a flat and neat bag shape. For household cleaning products, the package appearance directly affects the product’s market image.

4. No need to form bags from roll film

Because the customer uses premade bags, the machine does not need film forming, vertical sealing, or bag cutting from roll film. It focuses on bag feeding, opening, filling, and sealing, making it more suitable for customers who already have stable bag suppliers.



Key Technical Points for Laundry Powder Packaging

4-head weigher for 1kg and 2kg detergent powder

This project uses a 4-head weigher, which is more suitable for larger-dose laundry powder packaging than small auger fillers. Laundry powder usually has certain flowability and granule structure, so weighing-type filling is a better choice for this application.

Stable bag opening for flat premade bags

Premade four-side seal bags are relatively flat. For large bag sizes such as 230 × 310 mm and 270 × 350 mm, the bag opening system must be stable to reduce failed opening, powder overflow, or incomplete filling.

Reliable sealing for heavy powder bags

A 1kg or 2kg detergent powder bag needs strong sealing because the product weight is much higher than small sachets. Stable sealing temperature, sealing pressure, and sealing time are important to reduce leakage risk.

Dust control around filling and sealing area

Laundry powder can generate dust during filling. If powder remains on the sealing area, it may affect sealing strength. Therefore, the machine design needs to keep the filling process stable and reduce powder contamination near the bag mouth.
