For manufacturers looking for a compact and reliable solution for powder packaging, SEMA+ has recently completed a customized B-Level Sachet Packing Machine designed for automatic packaging of various powder products.
The machine combines vacuum feeding, automatic dosing, bag forming, filling, sealing and cutting in one continuous process. With a packaging speed of up to 30 pcs/min, PLC touch screen control and a durable 304 stainless steel structure, it provides a stable solution for small and medium-scale powder packaging production.
This B-Level Sachet Packing Machine is mainly designed for powder materials and can be customized according to the characteristics of the customer's product.
Typical applications include:
Milk powder
Protein powder
Coffee powder
Seasoning powder
Pharmaceutical powder
Cosmetic powder
Nutritional powder
Other free-flowing powder products
The filling system can be configured according to powder flowability, filling weight and package size to achieve more stable dosing performance.
The machine is equipped with an automatic vacuum feeder, which transfers powder from the material container directly into the machine hopper.
Compared with manual feeding, the vacuum feeding system helps reduce operator workload and makes continuous production more convenient.
It is particularly useful when the machine is used for longer production cycles or when the hopper is positioned at a higher level.
The machine operates at a packaging speed of approximately 30 pieces per minute, depending on the powder characteristics, filling volume, packaging material and sachet dimensions.
The automatic process includes:
Vacuum Feeding → Powder Dosing → Film Feeding → Bag Forming → Filling → Sealing → Cutting → Finished Sachet Output
This integrated packaging process helps manufacturers reduce manual handling and maintain more consistent finished package quality.
The customized machine produces back-sealed sachets with rounded corners.
The back-seal structure provides a neat and compact package appearance, while the rounded-corner design makes the finished sachet more comfortable to handle and gives the package a more refined appearance.
Package length, width, filling volume and printing design can be customized according to customer requirements.
The equipment adopts a PLC touch screen control system, allowing operators to adjust and monitor the main packaging parameters directly through the HMI.
The current machine is configured with Chinese and English operating languages, making operation more convenient for both domestic and overseas users.
Other interface settings can also be customized according to project requirements.
The overall machine body is manufactured from 304 stainless steel, providing good corrosion resistance, durability and convenient cleaning.
The stainless steel construction is suitable for food, pharmaceutical, health product and other powder packaging applications where equipment cleanliness and long-term durability are important.
The machine is designed for industrial use with a service life of more than 10 years under proper operation and routine maintenance.
Its robust stainless steel structure, stable electrical control system and durable mechanical components make it suitable for long-term continuous production.
Regular cleaning, lubrication, inspection and replacement of normal wearing parts can help maintain stable machine performance over its service life.
This customized B-Level Sachet Packing Machine has now been completed for the customer and is ready for the next stage of testing and delivery.
With vacuum feeding, 30 pcs/min packaging speed, PLC touch screen control, Chinese and English operating interfaces, back-seal rounded-corner sachets and 304 stainless steel construction, the machine provides a practical automatic solution for powder packaging manufacturers.
SEMA+ can also customize the machine according to different powder materials, sachet dimensions, filling weights and packaging requirements, helping customers build a packaging solution that better matches their actual production needs.
