How to choose stretch film?

In the food packaging industry, stretch film is widely used as an efficient and convenient packaging material. However, there are many types of stretch films on the market with varying quality. How to choose a stretch film that suits your needs has become the focus of many packaging material purchasing customers. This article will provide you with knowledge of the packaging material industry, help you better understand the stretch film, and make wise purchasing decisions.

1. Understand the basic principles and characteristics of stretch film

Stretch film, also known as stretch wrap or pre-stretch film, is a high-toughness plastic film. The stretch film uses the self-adhesiveness of the film itself and the heat shrinkage performance to compactly and fixedly bundle the products into a unit so that the scattered small pieces become a whole. Even in an unfavorable environment, the products will not be loose or separated, and there are no sharp edges and stickiness to avoid damage. The basic principle is to stretch the plastic packaging film through a stretching machine so that the film can tightly wrap the packaged items while maintaining a certain tension. Stretch film has excellent stretchability, retraction, self-adhesion, and good tear and puncture resistance, which can effectively protect the packaged items.

2. Clarify the demand for stretch film in food packaging

When choosing a stretch film, you first need to clarify the specific needs of food packaging. Different food types, shapes, weights, and transportation conditions will affect the choice of stretch film. For example, for fragile foods, you need to choose a stretch film with good cushioning properties; for foods that need to be kept fresh for a long time, you need to choose a stretch film with excellent sealing properties.

3. Compare different brands and models of stretch film

There are many brands of stretch films on the market, and each brand has its characteristics and advantages. When choosing, you can pay attention to some well-known brands of products and assist in decision-making by understanding their performance parameters, user reviews, and other information. In addition, different types of stretch films are also suitable for different packaging needs. You can choose the appropriate model according to the specific packaging items and scenarios.

4. Consider cost factors and cost performance

When choosing a stretch film, cost factors also need to be considered. The prices of stretch films of different brands, materials, and thicknesses will vary. As a purchasing customer, you need to reasonably control the purchasing cost while ensuring the packaging effect. It is recommended to compare the prices, performance, and other factors of different products and choose stretch film products with high-cost performance.

5. Focus on after-sales service and technical support

High-quality stretch film suppliers usually provide comprehensive after-sales service and technical support. When choosing a stretch film, you can pay attention to the supplier’s service quality, response speed, and problem-solving ability. This will help you get a better experience and support in the subsequent use process and ensure the smooth progress of the packaging work.

6. Focus on environmental factors and sustainable development

With the increasing awareness of environmental protection, more and more packaging material purchasing customers begin to pay attention to the environmental performance of products. When choosing a stretch film, you can pay attention to whether it is made of environmentally friendly materials and whether it is recyclable. Choosing stretch film products with good environmental performance can not only help reduce environmental pollution but also enhance the social image of the company.

Conclusion:

In summary, choosing stretch film requires comprehensive consideration of many factors, including basic principles, plastic packaging needs, food packaging needs, materials and performance, brands and models, cost factors, after-sales service and technical support, and environmental factors. By deeply understanding these factors, you will be able to choose stretch film products that suit your needs and provide strong support for the company’s food packaging work.
