Product Specifications

Product Application

GrainGuard green coffee bean airtight sample bag focuses on the full chain sample management of green beans, adapting to diverse core scenarios. The green coffee bean cosmetic sample bag is the standard choice for sample preservation in the coffee industry

1. Sample delivery for coffee trade: Exporters and traders from the production area send raw bean samples to buyers. During long-distance transportation, moisture and oxygen are isolated to prevent flavor loss and color darkening, ensuring that the sample is of the same quality as the bulk order and facilitating precise quality control and transaction completion.

2. Origin storage and sorting: Coffee plantations and processing plants are used for packaging and sample retention of beans from different production areas and batches. Sealed storage is used to avoid cross contamination and insect contamination, and batch samples are accurately retained to meet traceability management needs.

3. Roasting product control and research and development: After receiving green bean samples, roasting studios and factories store them for short-term cup testing and sampling to prevent oxidation from affecting flavor judgment; It can also be used for sample sealing in the development of new product formulas, stably preserving the original flavor characteristics.

4. Laboratory testing and traceability: Third party testing institutions and research institutions use sample packaging for testing indicators such as moisture content, defects, and flavor compounds in green beans. The airtight environment ensures accurate testing results and is suitable for cross-border traceability and quality certification scenarios.

5. Display of premium coffee brands: Used for displaying green bean samples in offline exhibitions and tasting events, transparent and visible+sealed to lock freshness, presenting high-quality green bean products intuitively, while avoiding the influence of humidity in the on-site environment on quality.

Product usage precautions

Proper use of GrainGuard green bean airtight sample bags can maximize the shelf life of green beans. The service life and preservation effect of green coffee bean cosmetic sample bags depend on standardized operations
1. Preparation before bagging: Ensure that the moisture content of the raw beans meets the standard (recommended 10% -12%), and there is no obvious moisture or impurities on the surface; Clean your hands or wear food grade gloves during operation to avoid contamination of raw beans or the inner wall of the bag with grease or stains on your hands, which may affect the sealing effect.
2. Bagging and sealing: After loading the green beans, gently squeeze the bag body to expel excess air, first tighten the airtight zipper to ensure complete closure, and then choose whether to heat seal according to the storage time (heat sealing is recommended for long-term storage); Control the temperature and time during heat sealing to avoid burning the bag body, and ensure a smooth and wrinkle free seal.
3. Storage environment requirements: After sealing, place in a cool, dry, and ventilated place, avoiding direct sunlight, high temperature and humidity environments (such as balconies and kitchens), and odor sources (such as spices and chemicals); Stay away from sharp objects to prevent puncturing the bag and damaging its airtightness.
4. Unzip and Reuse: Immediately tighten the zipper after each sampling. Short term reuse does not require heat sealing, while long-term storage requires secondary heat sealing; If the bag body is damaged, the zipper is loose, or the seal is ineffective, it should be replaced in a timely manner to avoid affecting the quality of the green beans.
5. Prohibition of illegal use: cannot be used for packaging non food grade items, cannot come into contact with strong acids, alkalis, or organic solvents; Do not steam or microwave at high temperatures to avoid material deformation and release of harmful substances.

FAQ

Q1: How long can GrainGuard airtight sample bags preserve green beans?
A1: In a standardized sealed, cool and dry storage environment, the green coffee bean cosmetic sample bag can maintain the original flavor and quality of raw beans for 3-6 months, far exceeding ordinary packaging; If stored under heat sealing for a long time, the shelf life can be extended to 8-12 months, depending on the initial moisture content of the beans and the storage environment.

Q2: Can sample bags be reused?
A2: Sure. The material of the bag body is tough and wear-resistant, and can be reused after cleaning the inner wall (removing residual soybean powder) without damage; But after multiple reuse, it is necessary to check whether the zipper and seal are loose. If the seal fails, it should be replaced in a timely manner to avoid affecting the preservation effect.

Q3: Can the brand logo or batch information be printed on the sample bag?
A3: Support. We provide customized printing services that can print brand logos, product information, batch numbers, traceability QR codes, and other content in designated areas of the bag body, helping customers achieve brand management and product traceability. The minimum customization quantity is flexible and adaptable to the needs of customers of different sizes.

Q4: Is the sample bag insect resistant?
A4: Yes. The green coffee bean cosmetic sample bag adopts a completely airtight structure to block the invasion of external pests; At the same time, a sealed environment will exhaust the oxygen inside the bag, inhibit the hatching of insect eggs and the survival of pests, without the need for additional fumigation treatment, safe and residue free, suitable for organic bean storage.

Q5: How to determine whether the airtightness of the sample bag is good?
A5: After sealing, gently press the bag body. If the bag body is tight and there is no air leakage or sound of air flow, it indicates good air tightness; If the bag body becomes loose, there is an airflow sound, or quickly rebounds when pressed, it indicates that the seal has failed and needs to be resealed or the sample bag needs to be replaced.
