Are you focused on manufacturing grains, granules, or powder? Chances are, sachets are your primary packaging solution. What machinery do you currently utilize for sachet packaging? It might be prudent to explore investing in a dedicated sachet packaging machine.
The advantages of selecting the appropriate packaging equipment are undeniable, particularly when procured from reputable manufacturers and suppliers. In this guide, we'll provide invaluable advice for selecting the optimal sachet packing machine.
Before delving into the sachet packaging machine buying guide, it's beneficial to understand what a sachet is. Essentially, it's a small packet typically crafted from thin plastic or paper material. Sachets find utility in both food and non-food applications, particularly for storing small grains and powder.
In contemporary usage, sachets are prevalent for preserving various items, including pharmaceutical drugs, herbs, spices, tea, cooking essentials like flour and sugar, baking mixes, nutritional supplements, and processed food pastes such as tomato paste, among others.
There are two main types of sachet packing machines. These are powder sachet packing machines and liquid packing machines.
The powder sachet packing machine is an automated device tailored for packing powders like tea, sugar, or flour. Its key advantage lies in its ease of loading sachets and adjustable parameters, catering to diverse packaging needs.
Constructed from stainless steel, this machine boasts durability, enabling prolonged operation with minimal wear and tear. However, it's not suitable for handling fluids or liquid substances. Additionally, it's designed to minimize dust generation and employs linear motor technology for efficient performance.
Liquid sachet packaging machine is designed for packing liquids and semi-fluids such as sauces, soups, and oils, the liquid sachet packaging machine offers similar durability and maintenance-free operation as its powder counterpart. Equipped with an external suction pump, it's adept at handling light materials like water or sauce.
A typical sachet packaging machine primarily comprises the following processes:
- Sachet filling
- Sachet sealing
- Sachet cutting & Sachet labeling units
Let’s delve into each of these activities:
This process involves filling sachets with materials. The sachet filling unit can be supplied with either pre-formed plastic bags or powdered materials.
When pre-formed cavities are supplied, the sachet packaging machine typically performs an air-blowing operation before filling the sachets.
The material is dispensed into the sachets directly from a weighing hopper through the sachet filling funnel, with the entry path into the sachet being either straight or curved, depending on the machine configuration.
In this step, two main functions are carried out:
1) Heat sealing: This primarily occurs at the bottom of the sachet package, where heat sealing prevents leakage and maintains the cleanliness and hygiene of the sachet. The sachet usually includes a temperature detector, which halts the heat sealing process once the sachet is filled with materials or products.
2) Punching: this is to punch some holes at both sides of the sachet pouch. For correct operation, a sachet filling machine generally uses either an air knife or a vacuum system.
These two steps are optional for different types of sachet packaging machines and they can be along with each other in one machine or in separate machines which work together.
This stage typically follows sachet sealing but precedes the sachets reaching the customer's hands. During this phase of the sachet packaging process, the sachet cutting and labeling units collaborate to ensure the sachet packages are of the correct size and easily identifiable for the products contained within.
Instead of utilizing bulk product tanks, sachets are filled into pre-heated metering pump tanks. This approach minimizes spillage and mixing between sachet materials, enhancing packing accuracy and production efficiency compared to volumetric feeding systems employed by other machines.
If you're in the market for the best sachet packaging machine, consider these invaluable tips before making your purchase:
1. Capacity: Determine the required capacity of the machine based on the volume of sachets needed within a given period. High-capacity machines suit large-scale operations, while smaller machines are ideal for small-scale producers. Consult with manufacturers to explore available sizes or inquire about customization options to match your productivity needs.
2. Machine Design: Opt for a machine with a simple design for ease of use and maintenance. The shape of the machine influences its overall appearance and functionality, so choose one that aligns with your preferences and operational requirements.
3. Custom Features: Consider any additional features that could streamline the sachet packaging process and enhance cost-effectiveness. Discuss with the manufacturer the possibility of incorporating custom features such as ejector pins to automate sachet placement and minimize damage during transport.
4. Power Consumption: Evaluate the power consumption of the machine and ensure compatibility with your power source. Machines designed for small batch operations typically consume less power compared to those intended for mass production.
5. Total Floor Area: Select a machine that minimizes floor space to optimize cost savings on real estate. Different machine orientations and sizes impact the total floor area required, so choose accordingly based on available space and operational needs.
6. Type of Machine: Choose a machine type that suits your product requirements, whether for liquid or solid materials. Consider the specific filling and sealing capacities of different machine types to ensure compatibility with your production needs.
7. Cost: Compare prices from various manufacturers and select a machine that offers the best value for your investment. Factor in performance, usage requirements, and affordability to make an informed decision.
8. Maintenance Cost: Assess the maintenance requirements of the machine, including availability of parts and manufacturer support. Machines that are easy to maintain typically incur lower maintenance costs over time, contributing to long-term savings.
