How to choose a divided glass food container manufacturer?

In many fields such as food storage, daily chemical packaging, home storage and medicine packaging, divided glass containers (also known as multi-grid glass jars) are favored for their excellent sealing, transparent and beautiful, and environmentally friendly and recyclable characteristics. For buyers, choosing a reliable divided glass container manufacturer is related to product quality, delivery cycle and even brand reputation.

There are many divided glass container manufacturers on the market, with a wide variety of products and uneven quality. So how can we accurately select truly trustworthy partners from many suppliers? This article will systematically analyze for you from five dimensions: production capacity, raw materials and processes, quality control, customization capabilities and services, price and delivery guarantees, to help you make a wise choice.

1. Look at the manufacturer's production capacity: Does it have the ability to supply large-scale and stable goods?

The first step to determine whether a divided glass container manufacturer is worth cooperating with is to examine its production capacity and infrastructure. You can start from the following aspects:

Factory scale and equipment support

Do you have large electric kilns, gas kilns, automated pipe drawing, blowing and molding equipment?

Do you have multiple automatic production lines to cope with batch orders?

Capacity performance

Can the monthly/quarterly output meet your needs?

Does it support parallel production of multiple models and specifications?

Worker technical level and experience

Are there long-term and stable skilled technicians?

Do you have more than 10 years of production experience?

Tips: You can ask the other party to provide factory videos, photos of production workshops, product flow charts, or arrange third-party factory inspection services for review.

2. Look at the raw materials and processes: Is high borosilicate glass used? Is there fine separation processing technology?

The performance of the separated glass container depends to a large extent on the raw materials and manufacturing processes used.

1. The quality of raw materials directly affects product quality

High-quality glass generally uses high borosilicate glass or high white material glass, which has:

High light transmittance

Strong resistance to cold and hot shocks

Smooth surface without bubbles and impurities

Poor-quality glass containers are prone to bubbles, variegated colors, cracks, and even break during high-temperature washing and ironing.

2. Is the separation process professional?

The divided glass container requires precise molding, tight partitioning and no leakage. The following processes are the key points:

One-piece molding process (the partition and the bottle body are integrated): high strength and long life.

Hot-melt splicing partition process: suitable for complex structures but requires high-temperature welding technology.

Precise mold control: ensure that the dimensions of multiple compartments are consistent, symmetrical and beautiful.

Tips: You can request samples to observe the transparency of the glass, the wall thickness, whether the partition is firm, and whether it is easy to clean.

3. Check the quality control system: Is there a complete quality inspection process and third-party certification?

A responsible manufacturer of divided glass containers must have a complete quality control system:

3.1 Is the internal quality control link strict?

Is it equipped with full-time quality inspectors?

Does each batch of products have a complete test report?

Are there items such as rupture tests, heat resistance tests, and sealing tests?

3.2 Has it passed authoritative certification?

ISO 9001 quality management system certification

SGS, FDA, LFGB and other food contact material certifications

RoHS environmental certification (if it involves the European and American markets)

Tips: High-quality manufacturers will proactively provide you with quality inspection records and certification documents, and welcome third-party agencies to conduct on-site inspections.

4. Look at customization and service capabilities: Can it meet the needs of diversified design and brand customization?

Different brands and application scenarios have different requirements for separated glass containers, for example:

Capacity differences: Commonly there are 100ml, 250ml, 500ml, 750ml, 1000ml and other specifications;

Number of divisions: Commonly double grids, three grids, four grids, six grids, etc.;

Sealing structure: glass cover + silicone ring, bamboo cover, plastic screw cover and other combinations;

Appearance design: Customized printing LOGO, color labels, frosting process, spray color, etc. are required.

Professional manufacturers should have the following service capabilities:

Provide fast proofing services, with sample delivery time not exceeding 7 days;

Have independent mold development capabilities and support non-standard product customization;

Provide design suggestions and packaging integration services (such as paper boxes, color cards, and foam lining customization);

Have cross-border e-commerce and export trade experience and support international transportation packaging specifications.

Tips: Excellent manufacturers are often equipped with product designers and foreign trade teams, which can greatly improve communication efficiency and development speed.

5. Look at price and delivery guarantee: Can the delivery date be guaranteed on the basis of a reasonable price?

5.1 Transparent price and high cost performance

Manufacturers of high-quality divided glass containers usually do not blindly lower prices, but provide cost-effective products at reasonable profits. They are willing to disclose:

Cost composition

Packaging solution costs

Freight quotation and shipping time estimate

5.2 Is the delivery commitment clear?

Is there a standard delivery date (such as delivery within 20 days)?

Is there any communication in advance in case of holidays or raw material price increases?

Can a contract be signed and the liability clause for delayed delivery be clearly stated?

5.3 Is the logistics capability mature?

Does it support multiple trade methods such as FOB, CIF, DDP, etc.?

Do you have a stable freight forwarder/customs clearance company?

Tips: You can start with a small batch trial order to test and evaluate the delivery capacity and supply stability.
