For marketing managers:

Bringing new products to the market is no easy undertaking — and as marketing managers know, how you position the product has a strong impact on how well it resonates. While packaging solutions play an integral role in how this story unfolds (for better or for worse), there isn’t always the bandwidth to create the ideal unboxing experience. With multiple product lines to oversee, marketing managers can’t spend all their efforts on each one, especially when there are fewer people available to do more work.

Unfortunately, this doesn’t always stop competitors. As more businesses prioritize the unboxing experience for customers and businesses alike, a lack of brand recognition on the exterior of a case or a disorganized inside can easily drive potential business in other directions. So while the product itself may be unique in value, a poor packaging solution that lacks innovation can fail to communicate how truly special your product is.

Q:How Weihanbag Helps Marketing Managers Win?
A: We can help you win through 4 aspects below.
1. AN EXTENSION TO YOUR TEAMAs a provider of custom cases, CBS breathes the same passion that you have for your products into the cases we produce. From the discovery session where we discuss your needs and goals to the moment your product is shipped, we guide you through every step of the way to ensure your business’s creative ideas turn into fully functional packaging solutions that elevate your brand.
2. POSITIVE BRAND RECOGNITIONFrom personalized touches to interactive elements, the custom cases we develop at CBS get your brand and your product recognized for the right reasons. With a positive unboxing experience from start to finish, your business can increase the perceived value of your product, improve your brand equity and boost customer loyalty.
3. BETTER ECONOMICSTo keep your business profitable and adhere to strict timelines and budgets, CBS uses design for manufacturing (DFM). While this technique ensures that manufactured cases look and perform as intended to balance the needs of various departments, it also leverages the most economical processes to minimize cost and deliver faster outcomes.
4. A COMPETITIVE EDGESince we’re an extension of your team, the focus on innovation is continual. Custom cases are developed with your future needs and goals in mind, and as new products emerge, you’ll have the resources and support to put ideas in motion. In a sea of brands vying for customers’ attention, this innovation takes away your headaches while pushing you toward the front of the pack.

For Product Managers:

As the guiding force behind the vision and strategy of a product, you have your hands full with overseeing so many moving parts. With all of the focus around the quality of the product itself, packaging solutions tend to become an afterthought — with economical solutions needed fast. This is especially true in today’s landscape where there are limited resources spreading product managers quite thin, on top of more timing and budget restrictions.

But packaging solutions aren’t just about speed-to-market. As product managers, you also want to be sure the product is distinctive and recognized for the right reasons. Just as a custom case should align with the positive unboxing experience that designers and marketers desire, it must also meet the technical specifications that engineers demand to achieve successful metrics.

Q: How can you help us do UNIQUE, BRANDED SOLUTIONS?
A: An extensive list of customization capabilities means that we can make your custom case a reflection of your brand as well as specify that it meets material, weight and environmental requirements. This balance satisfies the needs of the entire product team, while filling any gaps in technical knowledge that may create unneeded uncertainties on your end.

Q: How do you do to improve the SUPPLY CHAIN EFFICIENCY?
A: The design for manufacturing (DFM) approach that we use ensures that designs always translate into manufacturable products. In combination with the economical processes used, production schedules move faster without delays. This keeps you on schedule and within budget without exacerbating internal resources.

A: COLLABORATIONThe partnership that you create with us is fully based on the individual needs of your business. Whether you prefer us to take on the bulk of the design work or you have an in-house design team you’d like us to collaborate with, we’ll work closely with you to make sure all your ideas are weaved into the fabric of the solution — with our expertise provided where you need it.

Q: What's othe advantage if we work with you?
A: We have CONTINUOUS INNOVATION, Rather than keep creative ideas for packaging solutions on the shelf, having us as an extension of your team enables you to put these ideas into motion. As the unboxing experience becomes more dynamic with distinct packaging solutions, your business improves its brand equity and has another way to stand out from the competition.

For Sourcing agents

Sourcing managers have a lot of criteria to balance in purchasing activities — packaging solutions included. While suppliers need to work within the confinements of budgets and timelines, they must also be innovative and deliver high-quality custom case solutions. If one takes precedence over the other, businesses can suffer profit loss and have to go back to the drawing board to find replacements.

The tricky part is that many sourcing managers rely on multiple suppliers for a single custom case solution, from the design and manufacturing stages to the logistics of shipments. So they don’t just need to find these qualities in one supplier but rather several — and they have to oversee them all. The more supplier relationships there are to manage, the greater the workload, and the more chances there are for miscommunications and stalled production times.

Q:What can we get from you if we choose Weihan bag as our EVA case supplier?
1. INNOVATOR VS. SUPPLIERWhile CBS is a provider of custom cases, our real value is in how we design and engineer solutions to fit your specific needs. Rather than working from an existing template, we use our technical expertise to build custom solutions from the ground-up that balance creative demands with technical specifications. You save time, and get better results.
2. COST SAVINGSWith our design for manufacturing (DFM) approach, sourcing managers don’t have to worry about the scenario where a manufacturing supplier can’t replicate the work of an industrial designer. Innately designed to ease the manufacturing process, DFM delivers high-quality results at a cost-effective rate — a factor that helps you meet your savings goals.
3.ALL-IN-ONE SOLUTIONFrom the first conversation where we learn about your needs and goals to the moment your product ships, CBS handles every step of your custom case development. While this offers significant benefits in terms of production time and costs, our emphasis on customer service also simplifies communications and gets you answers to your questions fast.
4. IMPROVED SUPPLY CHAINAt CBS, we understand that if one part of the supply chain fails, the entire ecosystem feels the impact. That’s why we offer assistance every step of the way to streamline logistics, from custom labels to customer shipments. Our team stresses on-time delivery that saves you costs and also ensures that customers receive your product on time.
