The LooMak LPM-300 is an automatic roll-film packing machine for liquids and compatible semi-liquid products.
It forms pillow bags from packaging film, measures and fills the product, seals and cuts each bag, and completes the packaging cycle automatically.
With a listed measuring range of 20–300 ml and a packing speed of 40–70 bags per minute, the LPM-300 can be evaluated for products such as fruit juice, soy milk, yogurt, jelly and other flowable foods.
The product’s viscosity, temperature, particle content and required filling volume must be evaluated before the dosing system and final machine configuration are confirmed.

The values above are the currently listed standard specifications.
Actual packing speed depends on filling volume, product flow characteristics, bag dimensions, film material, sealing requirements and optional functions. The product-contact configuration, dosing method, electrical supply and film compatibility must be confirmed before ordering.
The LPM-300 can be evaluated for packing compatible liquid and semi-liquid products.
The machine may be used for portioned fruit-juice packaging when the product’s viscosity, temperature and particle content are suitable for the selected filling system.
Soy milk and similar beverages may be packed in small pillow bags after the required filling and product-contact configuration has been confirmed.
Flowable yogurt products can be evaluated according to their viscosity and filling temperature.
Products with fruit pieces, grains or other particulates require separate technical evaluation.
The LPM-300 may be configured for selected jelly or semi-liquid products that can move reliably through the dosing and filling system.
The actual product must be checked because highly viscous, sticky or heat-sensitive materials may require a different filling method.
Other potential applications include selected sauces, flavored drinks and compatible liquid foods.
Suitability should be confirmed through product information or a material test rather than assumed from the product name alone.
The LPM-300 combines several packaging stages in one automatic process.
Packaging film is supplied from a roll and guided into the bag-forming section.
The film width, thickness, structure and sealing properties must be compatible with the machine and product.
The film passes around the forming section and is shaped into a continuous tube.
The longitudinal seal creates the back-seal structure of the pillow bag.
The product is measured according to the selected filling volume.
The appropriate dosing system depends on product viscosity, temperature, foaming tendency and particle content.
The measured product is discharged into the formed package.
Stable product flow and suitable filling timing help reduce variation and contamination of the sealing area.
The machine forms the top seal of the completed bag and the bottom seal of the next bag.
Sealing temperature and time should be matched to the packaging film.
The sealed package is cut to the required length and discharged.
Bag counting can be completed as part of the automatic packaging cycle.
Production date and batch information can be added when a compatible coding device is included.
The current product description indicates that date coding requires a separate coding machine.
CTA: Confirm Your Product and Filling Method
The LPM-300 forms bags from roll film, measures the product, fills the bag, seals it and cuts the finished package.
This reduces the number of separate packaging steps required compared with manual filling and sealing.
The listed measuring range covers small portion packages from 20 to 300 ml.
Actual fill volume and accuracy must be confirmed for the specific product and dosing system.
The listed speed is 40–70 bags per minute.
Actual output depends on:
Filling volume
Product viscosity
Product temperature
Bag dimensions
Film structure
Sealing temperature
Coding requirements
Product flow stability
The standard configuration produces back-seal pillow bags.
The upper sealing width may be customized, subject to technical confirmation.
The machine uses a programmable control system for operating and adjusting packaging parameters.
Final control functions should be confirmed in the machine configuration.
The listed touchscreen interface supports:
Chinese
English
Russian
Spanish
The required interface language should be specified before ordering.
The current specification describes a 304 stainless-steel machine enclosure.
The material grade of all product-contact components should be listed separately in the final technical agreement.
The horizontal-sealing guide shaft is described as using specially processed bearing steel to support wear resistance, positioning and maintenance.
Before selecting the LPM-300, confirm the packaging material with the film supplier and machine manufacturer.
Provide the following information:
Film structure
Total film thickness
Maximum roll diameter
Film width
Printed or unprinted film
Registration-mark position
Required bag width
Required bag length
Seal width
Required barrier properties
Storage conditions
Product filling temperature
The currently listed film thickness is 0.04–0.08 mm, with a maximum film width of 300 mm.
The existing specification lists OPP/CPP, OPP/CE, MST/PE and PET/PE composite materials. These material abbreviations should be checked against the customer’s actual film specification before production.
The listed range is expressed in milliliters, which indicates volume rather than package weight.
Package weight depends on product density.
For example, 100 ml of one liquid may not have the same weight as 100 ml of a denser sauce or semi-liquid product.
When requesting a quotation, provide both:
Target filling volume in milliliters
Target net weight in grams, if applicable
Also provide the acceptable filling tolerance and product density when available.
Identify the exact product to be packed.
Indicate whether the material flows like water, juice, yogurt, syrup, sauce or gel.
A video showing the product flowing can help with preliminary evaluation.
State the expected temperature during filling.
Hot filling, ambient filling and chilled filling may require different configurations.
Confirm whether the product contains pulp, seeds, grains, fruit pieces or other solid particles.
Provide the minimum, maximum and most frequently used filling volumes.
Provide the required finished bag width, bag length and seal width.
Provide the complete laminated-film structure and thickness.
State the target number of bags per minute and the normal filling volume at that speed.
Describe the required cleaning method and frequency.
Do not assume that the standard machine includes automatic CIP cleaning unless this is explicitly confirmed in the technical agreement.
The LPM-300 and LPM-320 are designed for different product types.
